Boron Nitride (BN) micro powder

Boron nitride is refractory boron and nitrogen resistant to heat and chemically with the chemical formula BN. It exists in different crystalline forms that are isoelectronic to a carbon network of similar structure. The hexagonal shape corresponding to the graphite is the most stable and smooth between the BN polymorphs and, therefore, it is used as a lubricant and as an additive for cosmetic products. The cubic variety (sphalerite structure) analogous to the diamond is called c-BN; It is softer than diamond, but its thermal and chemical stability is superior. The rare modification of wurtzite BN is similar to lonsdaleite and could also be harder than the cubic form.

Because of the excellent thermal and chemical stability, boron nitride ceramics are traditionally used as parts of high-temperature equipment. Boron nitride has potential use in nanotechnology. You can produce BN nanotubes that have a structure similar to that of carbon nanotubes, that is sheets of graphene (or BN) rolled upon themselves, but the properties are very different.
