Frequently Asked Questions (FAQ)

Q What is Calcium-Stabilized Zirconia (Ca-PSZ) and how is it different from other zirconia types?
Calcium-Stabilized Zirconia (Ca-PSZ) is zirconia (ZrO₂) stabilized with calcium oxide (CaO) to maintain its cubic or partially stabilized crystal structure at room temperature. Compared to yttria-stabilized zirconia (YSZ), Ca-PSZ offers excellent thermal shock resistance and is more cost-effective, making it particularly suitable for high-temperature refractory and ceramic applications.
Q What are the main differences between the ceramic grade and refractory grade Ca-PSZ powders?
The ceramic grade Ca-PSZ (e.g., FR-3C01, FR-3C02) is produced using a special sintering process with precise CaO content control, resulting in high strength and thermal shock resistance ideal for thermal ceramics. The refractory grade (e.g., FR-ECZ01, FR-ECZ02) is produced via an electric melting quenching process, offering higher ZrO₂ purity and adjustable particle sizes, making it suitable for refractory linings, nozzles, and kiln furniture.
Q What is the maximum long-term service temperature for Ca-PSZ ceramic grade products?
The long-term service temperature varies by product code. The FR-3C01 and FR-3C01F grades are rated for up to 1200°C, while the FR-3C02 and FR-3C02F grades can withstand long-term service temperatures of up to 1500°C, making them suitable for more demanding high-temperature applications.
Q Can the particle size of the refractory grade Ca-PSZ powder be customized?
Yes. For FR-ECZ01 and FR-ECZ02 grades, the particle size can be adjusted according to customers' specific requirements. The FR-ECZO3 grade is available in hollow ball form. This flexibility allows the material to be tailored for a wide range of refractory and zirconia ceramic production processes.
Q In which industries is Ca-PSZ powder most commonly used?
Ca-PSZ powder is widely used across several industries including energy (solid oxide fuel cells), automotive and industrial sensing (oxygen sensors), steel and metallurgy (refractory linings, sizing nozzles, sliding plates), glass manufacturing (kiln furniture), and advanced ceramics. Its combination of high-temperature stability, ionic conductivity, and corrosion resistance makes it a versatile material across these sectors.
Q Why is Ca-PSZ preferred for solid oxide fuel cell (SOFC) electrolytes?
Ca-PSZ is preferred for SOFC electrolytes because of its high oxygen ion conductivity at elevated temperatures, which enables efficient migration of oxygen ions through the electrolyte layer. Combined with its mechanical robustness, structural stability under prolonged thermal cycling, and resistance to chemical degradation, it ensures reliable and long-lasting performance in fuel cell systems operating under demanding conditions.
