Production Method of Hexagonal Boron Nitride BN Powder

Chemical Vapor Deposition (CVD)

Boron – containing gases like boron trichloride (BCl3​) and nitrogen – containing gases such as ammonia (NH3​) are introduced into a reaction chamber. They react at high temperatures, typically around 1000 – 1500°C. The chemical reaction forms boron nitride on the substrate surface. For example, BCl3​+NH3​→BN+3HCl. This method allows for precise control over the structure and quality of the h – BN powder.

Sol-Gel Method

Boron – containing precursors like boric acid and nitrogen – containing organic compounds are mixed in a solvent. Through hydrolysis and condensation reactions, a gel is formed. The gel is then dried and heat – treated at 800 – 1200°C in an inert or nitrogen – rich atmosphere. This process results in the formation of h – BN powder.

Mechanical Milling

Boron and nitrogen – containing compounds or elements are milled together. High – energy ball milling is used to break and recombine the materials. The mechanical energy during milling promotes the formation of h – BN powder. The process is often carried out in an inert gas atmosphere to prevent oxidation, and it can take several hours to days to obtain the desired product.
