WebTo improve the commercial electrolysis of aluminum at high current density a modified bath with better electrical conductivity and better dissolution rate of alumina has been developed. The bath modified has been developed on the basis of sodium cryolite Na_3AlF_6 with additions AlF_3, KF, LiF, CaF_2, MgF_2. WebBoron Carbide. Boron carbide (B 4C) is the third hardest material after diamond and cubic boron nitride, which possesses low density, high degree of chemical inertness, high temperature stability, and excellent thermoelectric properties. The atomic structure of boron carbide is rather unique.
