Performance Advantages|Durability Under Extreme Thermal Conditions

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.

High-Temperature Engineering|Advanced Refractory Applications

In addition, calcium-stabilized zirconia powder plays a critical role in advanced refractory applications. It is widely used in high-performance refractory linings for furnaces, kilns, and other high-temperature equipment. Its exceptional resistance to thermal shock, corrosion, and chemical attack ensures long service life and operational reliability in extreme environments, such as those found in the steel, glass, and metallurgical industries.

Frequently Asked Questions
What is Ca-PSZ and how is it different from other zirconia materials?
Ca-PSZ stands for Calcium Partially Stabilized Zirconia. It is produced by incorporating calcium oxide (CaO) into the zirconia matrix to stabilize the crystal structure. Compared to unstabilized zirconia, Ca-PSZ offers significantly improved thermal shock resistance, mechanical strength, and structural stability at elevated temperatures, making it suitable for demanding industrial applications.
What are the main grades of Ca-PSZ powder available?
Ca-PSZ powder is primarily available in two grades: Ceramic Grade and Refractory Grade. The Ceramic Grade (e.g., FR-3C01, FR-3C02) is designed for high-strength thermal ceramic applications, while the Refractory Grade (e.g., FR-ECZ01, FR-ECZ02, FR-ECZO3) is produced via electric melting quenching and is used for high-temperature refractory products such as nozzles, kiln furniture, and sliding plates.
What is the maximum service temperature for Ca-PSZ ceramic grade products?
The long-term service temperature varies by product code. For FR-3C01 and FR-3C01F, the maximum service temperature is 1200°C. For FR-3C02 and FR-3C02F, the service temperature is rated up to 1500°C, making them suitable for more demanding high-temperature ceramic applications.
What industries commonly use Ca-PSZ refractory grade powder?
Ca-PSZ refractory grade powder is widely used across multiple industries including steel manufacturing, glass production, and metallurgical processing. Specific applications include electronic burning plates, sizing nozzles, sliding plates, invasive nozzles, and special kiln furniture — all of which require exceptional resistance to high temperatures, thermal shock, and chemical corrosion.
Can Ca-PSZ powder be used in solid oxide fuel cells (SOFCs)?
Yes. Calcium-stabilized zirconia powder is well-suited for use as an electrolyte material in solid oxide fuel cells. Its high ionic conductivity at elevated operating temperatures enables efficient oxygen ion migration through the cell, supporting stable and reliable electricity generation. Its mechanical robustness also ensures long-term performance under continuous thermal cycling.
Is the particle size of Ca-PSZ refractory grade powder customizable?
Yes. For 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 properties to suit different production processes and end-use applications. FR-ECZO3 is also available in a hollow ball form for specialized applications.
