Abstract
The production of ultrafine boron carbide powders from liquid boron-containing precursors and/or liquid carbon-containing precursors is disclosed. The liquid precursors are fed together or separately to a plasma system where the precursor materials react to form boron carbide in the form of ultrafine particles.
