Silicon Nitride Lumps

 

Silicon nitride (Si3N4 ) has an exceptional set of properties:

high hardness;

high corrosion resistance;

low density;

maintaining strength over a wide temperature range;

possibility of precision machining.

 

These combinations make the material indispensable in the production of corrosion-resistant, wear-resistant and heat-resistant products in a wide variety of industries.
