S 4-6 hours for reactive hot-pressing). The extreme temperature achieved during arc-melting means that both boron carbide (t melt 2450 C 18) and the dopant are both in the liquid phase, leading to rapid diffusion. Furthermore, the production of boron carbide powders using an electric arc furnace has been practiced since the early 1900s.
