Frequently Asked Questions (FAQ)

Q What is Ca-PSZ and how does it differ from other zirconia stabilizers?

Ca-PSZ stands for Calcium Partially Stabilized Zirconia. It uses calcium oxide (CaO) as the stabilizing agent to maintain the cubic phase of zirconia at room temperature, preventing destructive phase transformations. Compared to yttria-stabilized zirconia (Y-PSZ), Ca-PSZ offers a highly cost-effective solution for high-temperature refractory and ceramic applications while delivering excellent thermal shock resistance and durability.

Q What is the difference between Ca-PSZ ceramic grade and refractory grade?

Ceramic grade Ca-PSZ is produced via precise sintering with controlled CaO content, resulting in high-strength, high-toughness powder ideal for thermal ceramic components. Refractory grade Ca-PSZ is produced via electric melting quenching, yielding higher ZrO₂ purity and exceptional thermal stability for refractory linings, nozzles, sliding plates, and kiln furniture.

Q What is the maximum service temperature for Ca-PSZ ceramic grade products?

The Ca-PSZ ceramic grade products (FR-3C01 and FR-3C01F) are rated for long-term continuous service up to 1200°C, while the FR-3C02 and FR-3C02F grades can withstand operating temperatures up to 1500°C. Grade selection depends on the thermal demands of your specific operational environment.

Q Can the particle size of refractory grade Ca-PSZ powder be customized?

Yes. For FR-ECZ01 and FR-ECZ02 refractory grade products, particle sizes can be tailored according to specific application requirements. Additionally, the FR-ECZO3 grade is engineered in hollow ball form to suit lightweight, high-insulation refractory applications.

Q Which industries benefit most from using Ca-PSZ powder?

Ca-PSZ powder is extensively utilized across metallurgy (steel sizing nozzles, sliding plates), electronics (burning plates), clean energy (solid oxide fuel cell electrolytes), automotive (oxygen sensors), and industrial high-temperature processing (furnace linings and kiln components).

Q Why is Ca-PSZ selected for Solid Oxide Fuel Cell (SOFC) applications?

Calcium-stabilized zirconia exhibits high ionic conductivity at elevated operating temperatures, which is essential for SOFC electrolyte layers. It facilitates efficient oxygen ion transport while providing the mechanical robustness required for sustained high-temperature energy generation.
