Reade Advanced Materials - Boron Nitride Powder …

2020-12-21 · a) Hexagonal BN (h-BN) Ceramic BN crucibleHexagonal BN is the most widely used polymorph. It is a good lubricant at both low and high temperatures (up to 900 °C, even in an oxidizing atmosphere). h-BN lubricant is particularly useful when the electrical conductivity or chemical reactivity of graphite (alternative lubricant) would be problematic.

The vanadium-boron-nitrogen system - ScienceDirect

The assumption that boron does not dissolve to an appreciable extent in vanadium nitride was based upon the fact that the i45o sample gave the lattice parameter of the stoichiometric phase, and the fact that the vanadium borides, boron nitride, and boron do not crystallize in the f.c.c. structure exhibited by vanadium mononitride.

Phosphorus mononitride - WikiMili, The Free …

2019-12-15 · Boron nitride is a thermally and chemically resistant refractory compound of boron and nitrogen with the chemical formula BN.It exists in various crystalline forms that are isoelectronic to a similarly structured carbon lattice. The hexagonal form corresponding to graphite is the most stable and soft among BN polymorphs, and is therefore used as a lubricant and an additive to cosmetic products.

Nitride | chemical compound | Britannica

Nitride, any of a class of chemical compounds in which nitrogen is combined with an element of similar or lower electronegativity, such as boron, silicon, and most metals. Nitrides contain the nitride ion (N3−), and, similar to carbides, nitrides can be classified into three general categories:
