Product Description

Si3N4 Silicon Nitride Guide Roller for the Foundry Industry

Silicon nitride grinding discs, impeller blades are widely used in the field of powder grinding and are used as chassis.
Because silicon nitride ceramics are very hard, second only to diamonds and other materials, there is almost no loss during thegrinding process, and the impurities brought into the product are also minimal.
Although silicon nitride is a ceramic product, it has a good crystal structure, and the silicon nitride spherical product can well retain the crystal structure, so that the stress can be dispersed and the various metal ores can be broken.

 

Silicon Nitride (Si3N4) Characteristics: 1 Good thermal shock resistance 2 Creep resistance 3 Low density 4 High fracture toughness 5 High hardness and wear resistance 6 Electrical resistivity
