Specifications

Si3N4 ceramic is continuous and robust network structure because of its basic

structural unit [SiN4] tetrahedral construction.So it has the chacteriastics:

 

? Low coefficient of thermal expansion,

 

? High thermal conductivity

 

? Excellent thermal shock resistance
? Low density
? High strength and impact resistance
? wear resistance 
? Electrical resistivity
