Overview of Zirconium Boride  

 
Zirconium boride powder is a chemical substance and its molecular formula is ZrB2. Nature gray hard crystals. Zirconium boride has three components: zirconium monoboride, zirconium diboride, and zirconium tribromide. Only zirconium diboride is stable in a wide temperature range. Industrial production is mainly based on zirconium diboride. Zirconium diboride is a hexagonal crystal, gray crystal or powder, with a relative density of 5.8 and a melting point of 3040°C. High-temperature resistance, high strength at room temperature and high temperature. Good thermal shock resistance, low resistance, anti-oxidation at high temperature. The melting point is about 3000°C. With metallic luster.
 
Zirconium diboride powder(ZrB2) is a highly covalent refractory ceramic material with a hexagonal crystal structure. ZrB2 is an ultra-high temperature ceramic (UHTC) with a melting point of 3246°C. Coupled with a lower density of ~6.09 g/cm3 (the measured density may be higher due to ha impurities) and good high-temperature strength, it is suitable for high-temperature aerospace applications, such as hypersonic flight or rocket propulsion systems, for example, Furnace components, high-temperature electrodes, rocket engines, thermal protection structures for spacecraft with temperature capabilities exceeding 1800°C, and heavy-wear applications.
 
It is an unusual ceramic with relatively high thermal and electrical conductivity and has the same characteristics as the titanium diboride and diboride shares of the same structure. In addition to its fire resistance, good thermal conductivity (>50 W/m/K), inertness to molten metal, good thermal shock resistance, and high electrical conductivity (~105 S/cm), ZrB2 can also pass EDM basic ceramic molding.
 
ZrB2 parts are usually hot-pressed (applying pressure to the heated powder) and then machined to form. The covalent nature of the material and the presence of surface oxides hinder the sintering of ZrB2. The presence of surface oxides will increase the coarsening of crystal grains before densification during the sintering process. Pressureless sintering of ZrB2 is possible. Sintering additives such as boron carbide and carbon will react with surface oxides, thereby increasing the driving force for sintering, but the mechanical properties will decrease compared to hot-pressed ZrB2.

Zirconium diboride (ZrB2) is a highly covalent refractory ceramic material with a hexagonal crystal structure. ZrB2 is an ultra high temperature ceramic (UHTC) with a melting point of 3246 °C. This along with its relatively low density of ~6.09 g/cm3 (measured density may be higher due to hafnium impurities) and good high temperature strength makes it a candidate for high temperature aerospace applications such as hypersonic flight or rocket propulsion systems. It is an unusual ceramic, having relatively high thermal and electrical conductivities, properties it shares with isostructural titanium diboride and hafnium diboride.


How is Zirconium Boride Produced? 


ZrO2 and HfO2 are reduced to their respective diboron silanes by metal thermal reduction. Use cheap precursor materials and react according to the following reactions:
 
ZrO 2 + B 2 O 3 + 5Mg→ZrB 2 + 5MgO
 
The precursor materials for this reaction (ZrO 2 / TiO 2 / HfO 2 and B 4 C) are cheaper than those required for stoichiometric and boron thermal reactions. Prepare ZrB2 at a temperature higher than 1600°C for at least 1 hour through the following reaction:
 
2ZrO 2 + B 4 C + 3C→2ZrB 2 + 4CO
 
This method requires a slight excess of boron because some boron is oxidized during the boron carbide reduction process. It is also observed that ZrC is the product of the reaction, but if the reaction is carried out under an excess of 20-25% of B4C, the ZrC phase disappears and only ZrB2 remains. The lowest synthesis temperature (~1600°C) will produce UHTC with finer dimensions and better sinterability. Before boron carbide reduction, the boron carbide must be ground to promote the oxide reduction and diffusion process.


ZrO2 and HfO2 can be dispersed on the boron carbide polymer precursor before the reaction. in. Heating the reaction mixture to 1500°C results in the formation of boron carbide and carbon in situ, and the subsequent reduction of ZrO2 to ZrB2.


The gas phase is used to reduce the vapors of zirconium tetrachloride and boron trichloride when the substrate temperature is higher than 800°C. Recently, alternative ZrB2 films can also be prepared by physical vapor deposition.

Tantalum oxide is a compound with a high melting point, high chemical stability, and excellent electrical properties, widely used in fields such as electronics, optics, ceramics, etc. 1. Physical and chemical properties of tantalum oxideTantalum oxide (Ta2O5) is a white or light yellow powder with a high melting point (2980 ℃), high hardness (Mohs hardness of 7.5), and high chemical stability. Its molecular formula is Ta2O5, with a molecular weight of 337.83. Tantalum oxide is insoluble in water at room temperature but can dissolve in acidic and alkaline solutions.2. Preparation method of tantalum oxideDirect synthesis methodThe direct synthesis method involves reacting tantalum powder with high-temperature oxygen to produce tantalum oxide. This method is simple but requires high-temperature conditions and a slow reaction rate.Vapor deposition methodThe vapor deposition method reacts tantalum source gas with oxygen to generate tantalum oxide thin films at low temperatures. This method has high purity and density characteristics and is suitable for preparing high-performance tantalum oxide films.Sol-gel methodThe Sol-gel process is a method of preparing tantalum oxide through the Sol gel process. This way has the advantages of simple operation and low cost, but it needs to control conditions such as gel time and temperature.3. Application fields of tantalum oxideElectronic fieldAs a high-performance dielectric material, Tantalum oxide has a wide range of applications in electronics. For example, in manufacturing thin film capacitors, tantalum oxide is used as a dielectric layer, which has advantages such as high dielectric constant, low loss, and high stability. In addition, tantalum oxide can manufacture components such as gates and electrodes in electronic devices.Optical fieldTantalum oxide also has extensive applications in the field of optics. For example, tantalum oxide is used as a reflector or window component in optical waveguide devices, with advantages such as high reflectivity and low loss. In addition, tantalum oxide can also be used to manufacture optical thin films, gratings and other optical components.Ceramic fieldTantalum oxide also has extensive applications in the field of ceramics. For example, in high-temperature ceramic materials, tantalum oxide can be used as an additive or reinforcing agent to improve the material's mechanical properties and high-temperature resistance. In addition, tantalum oxide can also be used to manufacture high-performance ceramic products such as ceramic blades and bearings.4. Summary and OutlookAs a high-performance compound, Tantalum oxide has broad application prospects in fields such as electronics, optics, and ceramics. With the continuous progress of technology and the expansion of applications, the demand for tantalum oxide will continue to increase. Therefore, strengthening the research on the preparation technology and expanding the application field of tantalum oxide will be important research directions in the future. Meanwhile, with the continuous improvement of environmental awareness and the implementation of sustainable development strategies, the preparation technology of green environmental protection will also become an essential trend for future development.About RBOSCHCORBOSCHCO is a trusted global chemical material supplier & manufacturer with over 12 years experience in providing super high-quality chemicals and Nanomaterials.
