Silicon nitride

Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si 3N 4 is the most thermodynamically stable of the silicon nitrides. Hence, Si 3N 4 is the most commercially important of the silicon nitrides[4] when referring to the term "silicon nitride". It is a white, high-melting-point solid that is relatively chemically inert ...

Benefits of Silicon Nitride Milling Media

 · Benefits of Silicon Nitride Milling Media Silicon nitride is an extremely versatile material that can be formed into fully-densified spherical and pellet shapes through pressureless sintering. These ceramic balls represent extreme thermomechanical stability with highly tough grain boundaries, enabling them to resist fine particle abrasion and robust agitation within a revolving drum.
