1.1 Carbon tube furnace electric arc furnace carbothermal reduction

This is the most commonly used method, synthesis of boron carbide powder as early as the stoichiometric shortly after the B4C was identified (1934), electric furnace production of industrial research of boron carbide is successful, boron carbide as abrasive start has been applied in industry Elemental boron or a boron compound and carbon powder or carbon compounds into the high temperature after mixing equipment, such as carbon tube furnace or electric arc furnace, the flux in order to protect the gas or N2 under a certain temperature synthesis of boron carbide powder.
