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 (FAQ)

Q What is calcium-stabilized zirconia (Ca-PSZ) and how is it different from other zirconia materials?
Calcium-stabilized zirconia (Ca-PSZ) is a form of zirconia (ZrO₂) in which calcium oxide (CaO) is used as a stabilizing agent to maintain the cubic or partially stabilized tetragonal 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 refractory and high-temperature ceramic applications.
Q What are the main grades of Ca-PSZ powder available, and what are their differences?
Ca-PSZ powder is available in two main grades: the Ceramic Grade (e.g., FR-3C01, FR-3C01F, FR-3C02, FR-3C02F), which is produced via a special production process with controlled CaO content for high-strength thermal ceramics; and the Refractory Grade (e.g., FR-ECZ01, FR-ECZ02, FR-ECZO3), produced by electric melting quenching process, offering higher ZrO₂ purity and customizable particle sizes for industrial refractory products.
Q What is the maximum 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 ceramic applications.
Q Can the particle size of refractory grade Ca-PSZ powder be customized?
Yes. For FR-ECZ01 and FR-ECZ02 refractory grade products, the particle size can be adjusted according to customers' specific requirements. The FR-ECZO3 grade is available in a hollow ball form. This flexibility allows manufacturers to tailor the material to suit different production processes and end-product specifications.
Q What industries and products commonly use Ca-PSZ refractory grade powder?
The refractory grade Ca-PSZ powder is widely used in industries such as steel, glass, and metallurgy. Typical products include electronic burning plates, sizing nozzles, sliding plates, invasive nozzles, zirconia ceramic components, and special kiln furniture. Its high ZrO₂ content and superior thermal stability make it ideal for components exposed to extreme temperatures and corrosive environments.
Q Why is Ca-PSZ used in solid oxide fuel cells (SOFCs) and oxygen sensors?
Ca-PSZ exhibits high oxygen ionic conductivity at elevated temperatures, which is essential for both SOFCs and oxygen sensors. In SOFCs, it serves as the electrolyte layer, enabling efficient oxygen ion migration for stable electricity generation. In oxygen sensors, it accurately detects oxygen concentration in exhaust gases or furnace atmospheres, supporting precise combustion control, improved fuel efficiency, and reduced emissions.
