A facile reaction for the preparation of BN nanospheres

摘要

In this paper we describe the synthesis of nanocrystalline boron nitride (BN) with a hollow morphology by the reaction of NH{sub}4BF{sub}4 and NaNH{sub}2 at 500°C for 24h. Characterized by XRD, FTIR, XPS, TEM, and EDXA spectra, the composition and morphology of the products were confirmed. The possible formation mechanism was also discussed.
