Abstract:
Spherical boron nitride nanoparticles having an average particle diameter of less than 50 nm is obtained by a method of synthesizing spherical boron nitride nanoparticles including the following steps; heating a mixture of boric acid ester and nitrogen gas in ammonia gas and argon gas to form reaction product; crystallizing reaction product to form precursor of spherical boron nitride nanoparticles; and, heating the precursor in inert gas.
