🛡️

Thanks to its high melting point and strong resistance to corrosion and thermal stress, calcium-stabilized zirconia powder is widely used in applications that require long-term durability under elevated temperatures. It is commonly applied in advanced refractory materials, solid oxide fuel cells, oxygen sensors, and thermal barrier coatings, where materials must withstand continuous thermal cycling and aggressive chemical conditions without degradation.


Applications

Energy Applications|Solid Oxide Fuel Cell Electrolytes

One of the most important applications of calcium-stabilized zirconia powder is in solid oxide fuel cells (SOFCs). Its high ionic conductivity at elevated operating temperatures makes it an ideal choice for the electrolyte layer. The material allows oxygen ions to migrate efficiently through the cell, enabling stable and efficient electricity generation. At the same time, its mechanical robustness and structural stability ensure reliable operation under prolonged high-temperature conditions.

🔬
Sensing Technologies|Oxygen Sensors for Combustion Control

Another key application is in oxygen sensors, particularly those used in automotive exhaust systems and industrial process control. Calcium-stabilized zirconia serves as the core sensing material due to its ability to conduct oxygen ions at high temperatures. By accurately detecting oxygen concentration in exhaust gases or furnace atmospheres, these sensors enable precise combustion control, improving fuel efficiency while reducing harmful emissions.

Frequently Asked Questions (FAQ)
Q What is Ca-PSZ and how is it different from other stabilized zirconia?
Ca-PSZ (Calcium Partially Stabilized Zirconia) uses calcium oxide (CaO) as the stabilizing agent to prevent phase transformation in zirconia. Compared to yttria-stabilized zirconia (Y-PSZ), Ca-PSZ offers excellent thermal shock resistance and is more cost-effective, making it particularly suitable for refractory and high-temperature ceramic applications.
Q What are the main grades of Ca-PSZ powder available?
Ca-PSZ powder is primarily available in two grades: Ceramic Grade (e.g., FR-3C01, FR-3C01F, FR-3C02, FR-3C02F), designed for high-strength thermal ceramics with long-term service temperatures up to 1500°C; and Refractory Grade (e.g., FR-ECZ01, FR-ECZ02, FR-ECZO3), produced via electric melting quenching for use in refractory linings, nozzles, and kiln furniture.
Q What industries commonly use Ca-PSZ refractory grade powder?
The refractory grade Ca-PSZ powder is widely used in the steel, glass, and metallurgical industries. Typical applications include electronic burning plates, sizing nozzles, sliding plates, invasive nozzles, and special kiln furniture. Its high corrosion resistance and thermal shock resistance make it ideal for extreme industrial environments.
Q Can the particle size of Ca-PSZ refractory grade powder be customized?
Yes. For refractory grade products such as FR-ECZ01 and FR-ECZ02, the particle size can be adjusted according to customers' specific requirements. This flexibility allows manufacturers to tailor the material for different production processes and end-use applications, ensuring optimal performance in their refractory products.
Q Why is calcium-stabilized zirconia used in solid oxide fuel cells (SOFCs)?
Calcium-stabilized zirconia exhibits high ionic conductivity at elevated temperatures, which is essential for the electrolyte layer in SOFCs. It allows oxygen ions to migrate efficiently through the cell structure, enabling stable electricity generation. Its mechanical strength and structural stability also ensure long-term reliable performance under continuous high-temperature operation.
Q What is the maximum long-term service temperature for Ca-PSZ ceramic grade products?
The Ca-PSZ ceramic grade products are rated for long-term service temperatures of up to 1500°C (for FR-3C02 and FR-3C02F grades with CaO content of 3.5±0.2%). The FR-3C01 and FR-3C01F grades are suitable for long-term use up to 1200°C, making them appropriate for a broad range of thermal ceramic manufacturing applications.
