Wear-resistant high-hardness precision zirconia ceramic plate

Overview of Zirconia Ceramic Plates

Zirconia ceramics are a high-performance ceramic material with zirconium oxide (ZrO2) as the main component. It has the following characteristics: high strength, high toughness, high mechanics, fatigue resistance, corrosion resistance, high-temperature resistance, good chemical stability, compatibility and excellent heat resistance.

Zirconia ceramic plates are plate-shaped products of oxide ceramics with regular shapes and good dimensional stability. Based on processing and application. It inherits the relevant properties of zirconia ceramics and is widely evaluated in the fields of electronics, machinery, medicine and aerospace. For example, it is used for insulating parts and packaging materials in the electronics field, for wear parts and cutting tools in the machinery field, and for dental restorations and biomedical access in the medical field.

Features of Zirconia Ceramic Plates

Zirconia ceramic plate is a high-performance ceramic material with high strength and fracture toughness, excellent mechanical properties, high hardness and strong wear resistance, suitable for wear parts such as grinding tools. Its high melting point (about 2715℃) and excellent chemical stability make it perform well in high-temperature environments. It also has good electrical insulation and oxygen ion conductivity at high temperatures, biocompatibility, low thermal conductivity and a thermal expansion coefficient close to that of steel. These characteristics make it widely used in many fields, such as industry, medical care, and electronics. Specifications Table of Zirconia Ceramic Plates

FAQs of Zirconia Ceramic Plates

How does Zirconia Ceramic Plates work?

Q1:Is the zirconia ceramic plate easy to break?

Zirconia ceramic plates have good fracture resistance due to their high strength and high toughness. Its flexural strength can reach about 1200 MPa, and its fracture toughness is between 3.5 and 17 MPa·√m. These characteristics make it less likely to break or shatter when facing impact or stress than many traditional ceramic materials. Therefore, in applications such as cutting tools, bearings, and medical implants, zirconia ceramic plates can perform well and meet the needs of high-impact loads or frequent use.

However, as a ceramic material, it still has a certain degree of brittleness and there is a possibility of fracture under extreme impact or excessive stress conditions. In general, as long as its performance characteristics are fully considered during the design and use process and appropriate protective measures are taken, the risk of zirconia ceramic plates breaking can be effectively reduced.

Q2:What problems will be encountered in the processing of zirconia ceramics?

When processing zirconia ceramic plates, problems such as easy edge collapse and cracking of the material, severe tool wear, difficulty in heat dissipation leading to thermal stress concentration and deformation, and difficulty in achieving high precision and excellent surface quality may occur.

Q3：What are the requirements for processing zirconia ceramic plates?

When processing zirconia ceramic plates, it is required to use high-hardness tools, pay attention to cooling and heat dissipation, optimize processing parameters to control accuracy and surface quality, and perform necessary post-processing such as polishing.

Q4:What are the best processing methods for zirconia ceramic plates?

When processing zirconia ceramic plates, laser cutting and engraving technology can be used to achieve high-precision cutting. Water jet cutting is also a good choice, especially for cutting brittle materials, which can reduce the impact of thermal stress. In addition, precision grinding and polishing can improve surface finish and dimensional accuracy, while chemical mechanical polishing can further optimize surface quality to meet high-precision requirements.

Q5:What problems do zirconia ceramic plates often encounter during sintering?

Common problems during the sintering of zirconia ceramic plates include cracking, deformation, insufficient densification, abnormal grain growth, and high porosity.
