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

QWhat 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 lattice to stabilize its crystal structure. Unlike fully stabilized zirconia, Ca-PSZ retains a partially tetragonal phase, which contributes to its superior mechanical strength, toughness, and thermal shock resistance compared to other zirconia types.
QWhat are the main grades of Ca-PSZ powder available?
Ca-PSZ powder is available in two main grades: the Ceramics Grade (e.g., FR-3C01, FR-3C01F, FR-3C02, FR-3C02F), which is optimized for thermal ceramic manufacturing; and the Refractory Grade (e.g., FR-ECZ01, FR-ECZ02, FR-ECZO3), produced via electric melting quenching and used in high-temperature refractory applications.
QWhat is the maximum service temperature of Ca-PSZ ceramics grade products?
The ceramics grade Ca-PSZ products support long-term service temperatures of up to 1200°C for grades FR-3C01 and FR-3C01F, and up to 1500°C for grades FR-3C02 and FR-3C02F, making them suitable for a wide range of thermal ceramic applications.
QWhat industries commonly use Ca-PSZ refractory grade powder?
Refractory grade Ca-PSZ powder is widely used across the steel, glass, and metallurgical industries. Typical applications include electronic burning plates, sizing nozzles, sliding plates, invasive nozzles, zirconia products, and special kiln furniture — all of which require materials capable of withstanding extreme temperatures and aggressive chemical environments.
QCan the particle size of Ca-PSZ refractory grade powder be customized?
Yes. For grades FR-ECZ01 and FR-ECZ02, the particle size can be adjusted according to customers' specific requirements. Grade FR-ECZO3 is available in hollow ball form. This flexibility allows the material to be tailored for diverse manufacturing processes and end-use applications.
QWhy is calcium-stabilized zirconia used in solid oxide fuel cells and oxygen sensors?
Calcium-stabilized zirconia exhibits high ionic conductivity at elevated temperatures, enabling efficient oxygen ion migration — a critical property for both SOFC electrolytes and oxygen sensing elements. Its structural stability, mechanical robustness, and resistance to thermal cycling ensure reliable long-term performance in these demanding energy and sensing applications.
