Silicon nitride (Si3N4) ceramics are inorganic nonmetallic materials whose structural units are tetrahedrons, with each silicon atom at the center of the tetrahedron and each tetrahedron with four nitrogen atoms at its four vertices. These tetrahedrons share one silicon atom every three to form a continuous and robust network structure in three dimensions. This special structure gives silicon nitride many excellent properties, especially structural stability at high temperatures.

In the production of silicon nitride powder, silicon nitride grinding ball is an indispensable grinding medium and has been widely used. However, its use is far more than that, in the powder industry, silicon nitride grinding ball has good application value and a wide range of applications.

Main properties of silicon nitride (si3n4) ceramic grinding ball
The silicon nitride grinding ball has higher hardness and better wear resistance than the grinding ball of zirconia and alumina. The color of the silicon nitride grinding ball produced by our company is black and gray, and the shape is ball and column. Because of its very low consumption, the pollution of the grinding machine is greatly reduced. Silicon nitride (Si3 n 4) ceramic material has high hardness, high melting point, stable structure, high temperature resistance, cold resistance, wear resistance, corrosion resistance, anti-magnetic, insulation, oil-free self-lubrication and other characteristics, in addition to hydrofluoric acid, it does not react with other inorganic acids, strong corrosion resistance, high temperature oxidation resistance.
