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)

1 What is Ca-PSZ and how is it different from other zirconia materials?
Ca-PSZ (Calcium Partially Stabilized Zirconia) is a zirconia material stabilized using calcium oxide (CaO). Unlike fully stabilized zirconia, Ca-PSZ retains a partially tetragonal or monoclinic phase structure, which gives it superior mechanical strength, toughness, and thermal shock resistance compared to other stabilized zirconia variants such as Y-TZP or Mg-PSZ.
2 What are the main grades of Ca-PSZ powder available?
Ca-PSZ powder is available in two primary grades: the Ceramic Grade, produced through a special chemical process with controlled CaO content for high-strength thermal ceramics, and the Refractory Grade, produced by electric melting quenching for use in high-temperature refractory products such as sizing nozzles, sliding plates, and kiln furniture.
3 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 grades, the maximum service temperature is 1200°C. For FR-3C02 and FR-3C02F grades, the maximum long-term service temperature reaches up to 1500°C, making them suitable for more demanding high-temperature applications.
4 How is Ca-PSZ powder used in solid oxide fuel cells (SOFCs)?
In solid oxide fuel cells, Ca-PSZ serves as the electrolyte layer due to its high ionic conductivity at elevated temperatures. It enables efficient migration of oxygen ions through the cell structure, supporting stable electricity generation. Its mechanical robustness also ensures long-term reliability under continuous high-temperature operation.
5 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 for specialized refractory applications.
6 What industries commonly use Ca-PSZ refractory grade powder?
Ca-PSZ refractory grade powder is widely used across industries that involve extreme heat and chemical exposure. Key sectors include the steel industry (sizing nozzles, sliding plates, invasive nozzles), glass manufacturing, metallurgy, and electronics (electronic burning plates). Its excellent corrosion resistance and thermal shock performance make it a preferred material for special kiln furniture and other high-temperature equipment linings.
