Frequently Asked Questions (FAQ)

What is Calcium-Stabilized Zirconia (Ca-PSZ) and how is it produced?
Calcium-Stabilized Zirconia (Ca-PSZ) is a zirconia-based ceramic material in which calcium oxide (CaO) is used as a stabilizing agent to retain the cubic or partially stabilized crystal structure at room temperature. It is produced either through a special powder production process (for ceramic grade) or an electric melting quenching process (for refractory grade), allowing different grades with varying CaO content to be manufactured.
What is the difference between the Ceramic Grade and Refractory Grade Ca-PSZ?
The Ceramic Grade Ca-PSZ is produced via a special powder process with controlled CaO content, offering high strength, tenacity, and excellent thermal shock resistance — ideal for thermal ceramics. The Refractory Grade Ca-PSZ is produced by electric melting quenching and is designed for high-temperature industrial applications such as electronic burning plates, sizing nozzles, sliding plates, and special kiln furniture.
What are the main applications of Ca-PSZ powder?
Ca-PSZ powder is used across a wide range of industries and applications, including solid oxide fuel cells (SOFCs), oxygen sensors in automotive and industrial systems, advanced refractory linings for furnaces and kilns, thermal barrier coatings, and various zirconia ceramic products. Its high-temperature stability and ionic conductivity make it suitable for demanding environments in the steel, glass, energy, and metallurgical sectors.
What is the maximum service temperature for Ca-PSZ ceramic grade products?
The long-term service temperature depends on the specific product code. For example, FR-3C01 and FR-3C01F are rated for up to 1200°C, while FR-3C02 and FR-3C02F can withstand long-term service temperatures of up to 1500°C, making them suitable for more demanding high-temperature environments.
Can the particle size of refractory grade Ca-PSZ be customized?
Yes. For the refractory grade Ca-PSZ products such as FR-ECZ01 and FR-ECZ02, the particle size can be adjusted according to customers' specific requirements. This flexibility allows the material to be tailored for different manufacturing processes and end-use applications. FR-ECZO3 is also available in a hollow ball form for specialized applications.
Why is Ca-PSZ preferred over other stabilizers in high-temperature applications?
Calcium oxide (CaO) is a cost-effective and widely available stabilizer that effectively maintains the cubic phase of zirconia, providing excellent ionic conductivity, high melting point, strong corrosion resistance, and good thermal shock performance. These combined properties make Ca-PSZ a reliable and economical choice for solid oxide fuel cells, oxygen sensors, refractory linings, and thermal barrier coatings where long-term performance at extreme temperatures is critical.
