The starting materials for the synthesis of hexagonal boron nitride (HBN) powder typically include a boron source and a nitrogen source. The most common starting materials used for HBN powder synthesis are:
The choice of starting materials depends on factors such as availability, cost, purity requirements, and the specific synthesis method employed.
One of the most common synthesis routes for HBN powder involves the reaction between boric acid (H3BO3) or boric oxide (B2O3) as the boron source and ammonia (NH3) as the nitrogen source. The reaction typically takes place at high temperatures, ranging from 800°C to 1200°C, under an inert atmosphere or in the presence of a nitrogen-containing gas.
