bn crucible

Boron nitride can be used to manufacture crucibles for melting semiconductors and high-temperature containers for metallurgy, semiconductor heat dissipation and insulation parts, high-temperature bearings, thermocouple casings, and glass forming molds. ......

... carbide drills. Due to crystal stucture, BN is anisotropic electrically and mechanically. BN exhibits a high electrical resistance, low dielectric constant and loss tangent, low thermal expansion, chemical inertness, and good ......

...Crucible Boron nitride is a binary compound composed of the same number of nitrogen atoms (N) and boron atoms (B), and its empirical formula is BN. Boron nitride and carbon are isoelectronic, and like carbon, boron nitride has a variety of isomorphs, among which hexagonal boron nitride (α-BN) has a structure similar to graphite and is a very practical lubricant. Cubic boron nitride (β-BN......

...ceramic crucible Boron nitride ceramics can be used in the manufacture of high-temperature containers for metallurgical melting, semiconductor heat-dissipating insulation parts, high-temperature bearings, thermowells, and glass forming dies. BN is the only......
