Borazine      (BHNH)₃

Borazine is used for the formation of boron nitride films on the surface of different materials in various technologies. Its cubic phase is second only to diamond in hardness and a wide range of its characteristics predetermines it for improvement of cutting tools, electronic parts, etc.

Thermal stability: Extensive decomposition can occur when stored at ambient temperature for period longer than one month. Decomposition appears to be autocatalytic. Negligible decomposition when stored at below 0°C,

Stability to air: Stable in dry air but reacts with trace amount of atmospheric moisture. With liquid water reacts slowly to form H2, NH3 and boric acid.

Stability to light: Slow polymerization may occur by light. Hydrogen is formed as a by-product.

Borazine is flammable liquid which is decomposed by water, light, heat, alcohols and acids.
Fire extinguisher is carbon dioxide or dry chemicals as sand. Do not use water. Liquid may cause burns to skin, eyes and resp. system.
