Boron Nitride
Boron nitride is a refractory material with very high chemical resistance. It is insoluble in acids like HCl, HNO 3, H 2 SO 4, etc. but soluble in molten liquids of LiOH, KOH, NaOH, etc.Hence, the above compounds in general are used for etching boron nitride (BN). Boron nitride exists in a variety of crystalline modifications and among them the cubic and …Web
