Material Overview

Hexagonal Boron Nitride is a hexagonal crystal composed of nitrogen and Boron atoms, which has a graphite-like layer structure and appears as a loose, lubricious, moisture-absorbing, light white powder, so it is also called "white graphite". The theoretical density is 2.27g/cm³, specific gravity is 2.43, and Mohs hardness is 2.

Hexagonal Boron Nitride has good electrical insulation, thermal conductivity, and chemical stability.

Hexagonal Boron Nitride is insoluble in cold water, hydrolysis is very slow when boiling, and a small amount of boric acid and ammonia will be produced, it does not react with weak acids and strong bases at room temperature, but is slightly soluble in hot acids. It can only be decomposed by treatment with molten sodium hydroxide and potassium hydroxide.
