Boron Nitride Ceramics

Boron Nitride ceramics

Boron nitride is a heat- and chemically resistant refractory compound of boron and nitrogen with the chemical formula BN.it is softer than diamond, but its thermal and chemical stability is superior.Because of excellent thermal and chemical stability, boron nitride ceramics are traditionally used as parts of high-temperature equipment. Boron nitride has potential use in nanotechnology.
