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 Ca-PSZ (Calcium-Stabilized Zirconia) and how is it produced?
Ca-PSZ (Calcium Partially Stabilized Zirconia) is a zirconia-based ceramic material in which calcium oxide (CaO) is used as a stabilizing agent to maintain the cubic or tetragonal crystal phase at room temperature. It can be produced through either a special sintering process (for ceramics grade) or an electric melting quenching process (for refractory grade), allowing the CaO content to be adjusted to meet specific performance requirements.
Q What is the difference between Ca-PSZ ceramics grade and refractory grade?
The ceramics grade Ca-PSZ powder is produced via a special sintering process with tightly controlled CaO content, offering high strength, tenacity, and excellent thermal shock resistance — ideal for precision thermal ceramic components. The refractory grade is produced through an electric melting quenching process and is better suited for high-temperature industrial applications such as sizing nozzles, sliding plates, and kiln furniture, where bulk volume and structural durability are prioritized.
Q What are the main applications of calcium-stabilized zirconia powder?
Calcium-stabilized zirconia powder is widely used across multiple industries. Key applications include solid oxide fuel cell (SOFC) electrolytes, oxygen sensors in automotive and industrial systems, advanced refractory linings for furnaces and kilns, thermal barrier coatings, electronic burning plates, sizing nozzles, and special kiln furniture used in the steel, glass, and metallurgical industries.
Q What is the maximum service temperature of Ca-PSZ ceramic grade products?
The long-term service temperature depends on the specific product grade. For example, FR-3C01 and FR-3C01F are rated for up to 1200°C, while FR-3C02 and FR-3C02F can withstand long-term service temperatures of up to 1500°C. The higher CaO content in the 3C02 series contributes to improved stability at elevated temperatures.
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. FR-ECZO3 is available in hollow ball form, offering unique structural properties suitable for specialized refractory and insulation applications.
Q Why is calcium-stabilized zirconia preferred over other stabilizers in certain applications?
Calcium oxide is a cost-effective stabilizer that provides good ionic conductivity and satisfactory phase stability in zirconia. Compared to yttria-stabilized zirconia (YSZ), Ca-PSZ offers competitive performance in refractory and thermal applications at a more economical cost. Its high melting point, strong corrosion resistance, and reliable thermal shock performance make it a practical choice for large-scale industrial applications such as steelmaking, glass manufacturing, and energy systems.
