Production of boron carbide powder

摘要

The invention relates to a method of producing boron carbide powder. The method comprises (i) forming a liquid precursor from a carbon source; (ii) forming solid precursor particles from the liquid precursor; (iii) subjecting the solid precursor particles to pyrolysis; and (iv) subjecting the pyrolysed solid precursor particles to a carbothermal reduction process. A boron source is introduced during one of steps (i) to (iv) such that the carbothermal reduction process results in the production of boron carbide powder.
