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
Q What is Ca-PSZ and how does it differ from other zirconia materials?
Ca-PSZ stands for Calcium Partially Stabilized Zirconia. It is produced by incorporating calcium oxide (CaO) into the zirconia crystal structure to partially stabilize the tetragonal or cubic phase. Compared to unstabilized zirconia, Ca-PSZ offers significantly improved resistance to thermal shock, higher mechanical strength, and better structural stability at elevated temperatures, making it suitable for demanding ceramic and refractory applications.
Q What are the main differences between the ceramic grade and refractory grade Ca-PSZ?
The ceramic grade Ca-PSZ is produced through a special production process with adjusted CaO content, resulting in high strength, tenacity, and excellent thermal shock performance — ideal for manufacturing thermal ceramics. The refractory grade Ca-PSZ is produced via electric melting quenching, offering higher ZrO₂ purity and is primarily used for industrial refractory products such as sizing nozzles, sliding plates, and special kiln furniture.
Q What is the maximum long-term service temperature for Ca-PSZ ceramic grade products?
The Ca-PSZ ceramic grade products, such as FR-3C02 and FR-3C02F with a CaO content of approximately 3.5%, can withstand long-term service temperatures of up to 1500°C. Lower CaO content grades like FR-3C01 and FR-3C01F are rated for up to 1200°C continuous use.
Q How is Ca-PSZ powder used in solid oxide fuel cells (SOFCs)?
In solid oxide fuel cells, Ca-PSZ powder serves as the electrolyte layer material. Its high ionic conductivity at elevated operating temperatures enables efficient oxygen ion migration through the cell, supporting stable electricity generation. The material's mechanical robustness and structural stability also ensure reliable long-term performance under continuous high-temperature operating conditions.
Q Can the particle size of refractory grade Ca-PSZ be customized?
Yes. For the refractory grade Ca-PSZ products FR-ECZ01 and FR-ECZ02, the particle size can be adjusted according to customers' specific requirements. This flexibility allows the material to be tailored for various refractory and ceramic manufacturing processes, ensuring compatibility with different production needs.
Q What industries commonly use Ca-PSZ powder in their production processes?
Ca-PSZ powder is widely used across multiple high-temperature industries. Key sectors include steel manufacturing (sizing nozzles, sliding plates), electronics (electronic burning plates), energy (solid oxide fuel cells), automotive (oxygen sensors for exhaust systems), glass and metallurgical industries (furnace linings and kiln furniture), as well as advanced ceramics manufacturing requiring high thermal shock resistance.
