Nitride Compounds, Powder-Wurtzite Boron Nitride-W-Bn

Nitride Compounds, Powder-Wurtzite Boron Nitride-W-Bn

Description

The next generation of boron nitride materials. It is manufactured by detonation. It has a polycrystalline structure that provides superior cutting properties and. moreover, sharpens itself during cutting.

Chemical Name: Wurtzite boron nitride

Chemical Formula: w-BN

Preparation of Wurtzite Boron Nitride: Wurtzite BN can be obtained via static high-pressure or dynamic shock methods. The limits of its stability are not well defined. Both c-BN and w-BN are formed by compressing h-BN, but formation of w-BN occurs at much lower temperatures close to 1700 °C.

Synonyms

wurtzite boron nitride powder, w-BN, CAS# 10043-11-5,

Chemical Properties

Standard Grade: Boron nitride= <98.00%, w-BN= <95.00% and Hexagonal boron nitride= >3.00%

Premium Grade: Boron nitride= <99.00%, w-BN= <98.00% and Hexagonal boron nitride= <1.00%

Physical Properties

Wurtzite boron nitride is produced in two different particle shapes: plate and regular crystal

Typical Applications

a) For sintering coarse grit polycrystalline structure powders, which are later used for manufacturing traditional cutting and grinding tools. Cutting inserts made from Wurtzite boron nitride material have high shock resistant properties superior to regular polycrystalline CBN. It is an excellent material for steel polishing applications such as molds, dies, etc.

b) Wurtzite Boron Nitride with plate shape particles is used as a raw material for sintering coarse grit polycrystalline structure powders, which are later used for manufacturing traditional cutting and grinding tools. The cutting inserts made from Wurtzite Boron Nitride material have high shock resistant properties superior to regular polycrystalline CBN.

c) Wurtzite Boron Nitride with regular crystal shape particles is the perfect material for steel polishing applications, such as, molds, dies, etc.
