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. <br><br> SPECIFICATIONS: <br> - Material: Hexagonal Boron Nitride (hBN, boron nitride, "white graphite") <br> - Purity: 98% <br> - 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).<br> - Color: White <br> - Coefficient of Friction (COF): as low as 0.15 <br> - Density: 2.3 gms/cc - Hardness: Approx. 1-2 on Moh's hardness scale<br><br> NOTE: The Hexagonal Boron Nitride (hBN) product offered here is NOT cosmetic grade and has not been tested for use in cosmetics or any other regulated use.
