Zirconia ceramics are mainly used in the production of capacitors, sensing elements and insulators in the electronics field. These ceramic capacitors are prized for their high dielectric constant and low loss, effectively improving the performance and energy efficiency of electronic products. In addition, zirconia ceramic sensors are used in a wide range of applications, including environmental monitoring and industrial automation, due to their excellent sensitivity and stability.

Zirconia ceramics act as an insulating component in electronic devices, preventing current leakage and short-circuit events. Such applications significantly improve the stability and safety of equipment and advance the development of electronics.

Zirconia ceramics are used in a wide range of chemical applications, especially in catalyst carriers, reaction facilities and piping systems. Thanks to their high specific surface area and excellent thermal stability, the ceramics significantly enhance catalytic performance and selectivity. In addition, the material’s use in corrosion-resistant environments effectively extends the service life of equipment such as reactors and piping.

Zirconia ceramics are a key material for seals and valves in chemical equipment. With its excellent mechanical strength and corrosion resistance, it performs well under high pressure and aggressive conditions, making it the ideal material of choice.

Zirconia Ceramics Preparation Technology

Zirconia ceramics are produced using a variety of manufacturing techniques such as powder metallurgy, chemical vapor deposition and sol-gel. Powder metallurgy technology is the primary method to create dense ceramic parts by sintering compressed zirconia powders at high temperatures. Chemical vapor deposition and sol-gel techniques, on the other hand, specialize in producing high-quality, uniform zirconia ceramics.

The properties of zirconia ceramics continue to improve with the continuous development of the preparation process. For example, by optimizing the sintering conditions, ceramics with specific crystal structures can be synthesized to suit a wide range of application scenarios.
