Design Features

High Mechanical Strength

Silicon nitride ceramics possess exceptional hardness and impact resistance. They can withstand significant mechanical stress without fracturing or deforming, 

making them suitable for applications subject to high-stress conditions.

Excellent High-Temperature Resistance

This material remains stable at temperatures exceeding 1200°C, making it ideal for the construction of high-temperature equipment and systems, thanks 

to its superior thermal stability.

Low Coefficient of Thermal Expansion

With a low coefficient of thermal expansion (3.1×10⁻⁶/°C), the material maintains stability even in environments with drastic temperature fluctuations, 

making it well-suited for use in heat exchangers and as linings for high-temperature furnaces.

Good Wear Resistance

Hot-pressed silicon nitride ceramics exhibit high resistance to wear, ensuring a long service life even under conditions involving significant friction.

Excellent Thermal Conductivity

Despite its high mechanical strength, silicon nitride ceramic retains excellent thermal conductivity, making it suitable for use in heat dissipation systems 

and heat exchange equipment.

Electrical Insulation Properties

This ceramic material offers excellent electrical insulation, making it appropriate for use as a substrate in electrical equipment and for other applications 

requiring electrical isolation.

Application Areas

Hot-pressed silicon nitride ceramic polishing sheets offer vital solutions across various high-tech industries due to their high-performance characteristics and 

stability. They provide irreplaceable advantages, particularly in applications requiring resistance to high temperatures, heavy loads, and intense friction, as well 

as those demanding electrical insulation.

Heat Exchangers

Leveraging their high thermal conductivity and thermal stability, these sheets serve as partition plates in heat exchangers, enhancing energy efficiency and thermal 

management performance.

Combustion Chamber Linings

Used in high-temperature environments—such as combustion chambers—they provide heat resistance and protective properties, thereby extending the service 

life of the equipment.

Semiconductor Manufacturing

In semiconductor manufacturing, especially during high-temperature processes, these sheets are used to protect and isolate sensitive components, preventing 

thermal damage and chemical corrosion.
