A chemical model for the formation of nanosized turbostratic boron nitride powder from urea is proposed. The mechanism is based on the interaction of metaborate acid O=B—OH with urea (NH2)2CO. When OH groups are replaced by NH2 groups, H2O and CO2 are released. Metaboryl amide O=B—NH2 formed in the replacement process is studied. It is found that dehydration of the compound releasing >B—N< radicals promotes the subsequent formation of turbostratic boron nitride.
