1. Overview of Tungsten Boride Powder

Tungsten Boride Powder is an inorganic compound powder synthesized by high-temperature reaction of tungsten (W) and boron (B). Its common phases mainly include WB, WB₂ and W₂B₅. Among them, WB₂ and W₂B₅ are the most widely used due to their strong stability and excellent performance. It appears as silver-gray or black powder, with uniform particle size and good dispersibility. It is insoluble in water, chemically stable at room temperature, and not easy to react with common acids and alkalis. It only reacts slightly with strong oxidants at high temperatures. These characteristics make it an indispensable key material in the field of high-end manufacturing.

1.1 Core Physical and Chemical Properties

1. Ultra-high hardness and excellent wear resistance: The Vickers hardness of tungsten boride powder ranges from 36 to 41GPa, which is much higher than that of tungsten carbide (22-30GPa) and close to that of diamond and cubic boron nitride. Its hardness remains stable at high temperatures, making it not easy to wear and deform. Compared with diamond, tungsten boride does not cause carburization during processing, has better oxidation resistance, and does not require high pressure during synthesis, which greatly reduces production costs and is more suitable for large-scale production applications. This property makes it the core raw material for preparing wear-resistant coatings, cutting tools, molds and other products, which can significantly improve the service life and work efficiency of products and reduce subsequent maintenance costs.

2. Excellent high temperature resistance for extreme environments: The melting point of tungsten boride powder is as high as 2365℃, the long-term working temperature can reach 800℃, and it can withstand 1200℃ high temperature in the short term. It does not soften or decompose at high temperatures, and has good thermal stability and thermal conductivity (thermal conductivity is close to that of metallic aluminum). It can stably perform in high-temperature components in the aerospace field, as well as high-temperature furnaces and thermal barriers in the metallurgical and chemical fields, solving the problem that ordinary materials are easily damaged and have a short service life in extreme high-temperature environments.

3. Strong corrosion resistance, oxidation resistance and stability: Tungsten boride powder has strong chemical inertness, which can resist the erosion of strong acids, strong alkalis and organic solvents. It also has excellent oxidation resistance, which is not easy to oxidize and discolor in the air, and can maintain stable performance for a long time. In addition, it has good neutron absorption capacity and γ-ray shielding performance, which can also play an important role in the nuclear industry, further expanding its application scope.

4. Dual properties of metal and ceramic for multi-functional applications: Tungsten boride powder breaks the limitations of traditional ceramic materials with poor conductivity and metal materials with insufficient hardness. It has both the high hardness and high temperature resistance of ceramics and the excellent electrical conductivity of metals (electrical conductivity can reach 5.3×10⁴ S/cm, close to that of aluminum bronze alloy). This unique combination of properties enables it to be used as a structural material to withstand high strength and high wear, and also as a functional material in electronic devices, electrodes and other fields, realizing multi-scenario application needs.

1.2 Product Specifications

As a professional foreign trade supplier, we understand the different needs of customers in different industries. We have established a diversified product specification system and can provide customized tungsten boride powder products according to the specific application scenarios of customers. The core specifications are as follows (can be adjusted on demand):

1. Purity specification: The conventional purity is 99.0%~99.99%, and the high purity can reach 99.999%. The impurity content is strictly controlled below 1ppm, which effectively avoids the impact of impurities on product performance. It is suitable for high-end electronics, aerospace and other fields that require extremely high material purity.

2. Particle size specification: The conventional particle size is 1μm~50μm. We can customize nano-scale (50nm~100nm), sub-micron scale (100nm~1μm) and coarse particle scale (50μm~150μm) powders. The particle size distribution is uniform, with good dispersibility and no agglomeration, which meets the needs of different forming processes (sintering, spraying, coating, etc.).

3. Phase specification: We can provide single-phase or mixed-phase tungsten boride powders of WB, WB₂ and W₂B₅. Among them, WB₂ is the most mainstream product type due to its strong stability and great application potential. The phase ratio can be accurately adjusted according to customer application needs. It should be noted that WB₄ has poor thermal stability and starts to decompose into WB₂ at around 1200℃, so it is not suitable for large-scale industrial application^{(1)}.

4. Packaging specification: We adopt various packaging methods such as 1kg aluminum foil bag & fluorinated bottle, 10kg aluminum can & carton, 25kg cardboard drum & woven bag & plastic bucket. The packaging is sealed and moisture-proof, which can effectively prevent the powder from oxidation and moisture. It also meets international transportation standards to ensure that the products are intact during long-distance transportation. We support customized packaging labels and specifications.

2. Preparation Process and Quality Control

The performance of tungsten boride powder directly depends on the preparation process and quality control level. At present, the mainstream preparation methods in the industry mainly include high-temperature solid-state synthesis method, chemical vapor deposition (CVD), plasma-assisted synthesis method, mechanical alloying and ball milling method, borothermal reduction method, etc. Each method has its own advantages and disadvantages, and is suitable for the preparation of products with different specifications and uses^{(5)}.

Combined with years of industry experience, we have optimized and integrated the preparation process, adopting the whole-process production mode of “raw material purification – precise proportioning – high-temperature synthesis – crushing and classification – purity detection – sealed packaging”, to ensure that each batch of products meets international standards and customer needs.

2.1 Core Preparation Process

1. Raw material purification: We select high-purity tungsten powder (purity ≥99.99%) and boron powder (purity ≥99.99%) as raw materials. Impurities such as iron, copper and silicon in the raw materials are removed through vacuum distillation, chemical purification and other processes to ensure that the raw material purity meets the standard and guarantee product quality from the source. We have established a strict raw material procurement and screening system, and established long-term cooperation with global high-quality raw material suppliers to ensure stable raw material supply and controllable quality. At the same time, we rely on professional raw material testing equipment to strictly test each batch of raw materials, and unqualified raw materials are never used.

2. Precise proportioning: According to the phase and performance requirements of customers, we use precision metering equipment to uniformly mix tungsten powder and boron powder according to a specific molar ratio (for example, when preparing WB₂, the molar ratio of tungsten to boron is close to 1:2). The mixing process is protected by inert gas to avoid oxidation of raw materials and ensure mixing uniformity, laying a foundation for subsequent high-temperature synthesis. We have mature proportioning schemes for different phases of tungsten boride powder, which can accurately adjust the proportion of each element to ensure the stability and consistency of product performance.

3. High-temperature synthesis: We adopt the high-temperature solid-state synthesis method as the core preparation process. The uniformly mixed raw materials are put into a vacuum or inert gas protected furnace, and the temperature is controlled at 1800℃~2200℃ for 3~8 hours to make tungsten and boron fully react chemically to form tungsten boride compounds. Compared with other preparation methods, the high-temperature solid-state synthesis method has the advantages of mature technology, low production cost, large output and high product purity, which is suitable for large-scale production^{(7)}. At the same time, we can flexibly adjust parameters such as reaction temperature and time according to product specifications to optimize product performance. For example, when preparing nano-scale tungsten boride powder, we can combine plasma-assisted synthesis method to improve the dispersibility and fineness of the powder.

4. Crushing and classification: The synthesized tungsten boride bulk is crushed by high-precision crushing equipment (such as jet mill), and then classified by classification equipment. Powders of different particle size specifications are screened according to customer needs to ensure uniform particle size distribution and no large particle impurities. The crushing process is also protected by inert gas to prevent powder oxidation. At the same time, the crushing force is strictly controlled to avoid powder agglomeration and improve product dispersibility.

5. Purity detection: After crushing and classification, the powder is sent to a professional detection center for purity detection. We use advanced detection equipment such as inductively coupled plasma mass spectrometry (ICP-MS) and X-ray diffraction (XRD) to accurately detect the purity, impurity content and phase composition of the powder. Only the products that pass all the detection indicators can enter the next process. We will provide a detailed detection report for each batch of products for customers’ reference.

6. Sealed packaging: The qualified powder is packaged in a clean and dry environment. The packaging materials are selected with high-quality materials that are corrosion-resistant and moisture-proof. After packaging, the air in the package is extracted and filled with inert gas to further prevent the powder from oxidation and moisture. Each package is labeled with product information such as product name, specification, purity, production date and batch number for easy traceability.
