Effects of reaction parameters on boron carbide powder production by the carbothermic process

Experiments were carried out to determine suitable reaction parameters for carbothermic production of boron carbide from relatively fine reactants and relatively low temperatures, compared with traditional production in an Acheson furnace or in an electric arc furnace. Effects of carbon type and particle size, boron oxide particle size, boron oxide‐to‐carbon ratio, and temperature were determined.
