Silicon nitrideWikipedia
Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si 3 N 4 is the most thermodynamically stable of the silicon nitrides. Hence Si 3 N 4 is the most commercially important of the silicon nitrides when referring to the term "silicon nitride". It is a white high-melting-point solid that is relatively chemically inert being attacked by dilute HF and hot H
