Silicon nitride ceramic bushing sleeve has low thermal expansion coefficient and high thermal conductivity, so it has excellent heat shock resistance. 

Within 1200℃ temperature, silicon nitride ceramics have high strength and impact resistance.

Silicon Nitride (Si3N4) shows us the greatest cross-sections of material properties across the technical ceramic groups, this makes it a structural ceramic with the best comprehensive properties, 

and able to provide specialist solutions for those harshest industrial working conditions on earth.

In recent years, silicon nitride ceramics have made great strides in a number of industrial applications, which allowed great flexibility and customization to create precisely the parts needed.
