Abstract
A chemical synthesis method to fabricate boron carbide to obtain boron carbide fine powders includes the steps of: (A) formulating a precursor solution including a boron source, a liquid organic carbon source and a catalyst; (B) subjecting the precursor solution to a pyrolytic reaction in the presence of electromagnetic radiation to obtain a boron carbide precursor; and (C) subjecting the boron carbide precursor to a thermal energy treatment in the presence of thermal energy to obtain boron carbide fine powders.
