Product Review

Hexagonal Boron Nitride, also known as just Boron Nitride or hBN and sometimes called "white graphite," is a chemical compound that is produced from boron compounds in a high temperature reaction. It is one of the most lubricious materials known. With a coefficient of friction as low as 0.15, and being "cleaner" to use than molybdenum disulfide and tungsten disulfide, it is a superb dry lubricant for many applications, particularly bullet and gun barrel coating.

SPECIFICATIONS:
- Material: Hexagonal Boron Nitride (hBN, boron nitride, "white graphite")
- Purity: 98%
- Average Particle Size (APS): 0.5 micrometers (microns, µm, micrometers), approximately 12000 mesh equivalent ("mesh" is a measure of the fineness of a material separation screen, but due to the impossibility of weaving such fine wires or filaments to produce such a fine screen there are no actual screens with mesh finer than 600 available, so the number is for relative particle size comparison only).
- Color: White
- Coefficient of Friction (COF): as low as 0.15
- Density: 2.3 gms/cc - Hardness: Approx. 1-2 on Moh's hardness scale
