Silicon nitride ceramics have the characteristics of high strength and toughness, good impact resistance, high hardness and excellent wear resistance.
The acicular and columnar crystal structure ensures that its wear resistance is more than 10 times that of alumina ceramics.
Excellent heat resistance and corrosion resistance, ranking first in the field of ceramics.
Under normal conditions, the density of silicon nitride is only 3.2g/cm ³。
