抄録

An aluminum-boron alloy containing high boron concentration has been synthesized by the reaction of aluminum and potassium fluoroborate at 700-830°C. The heat of the reaction is calculated to be 559.0kJ/mol and the temperature of the synthtic reaction must be controlled below 830°C. Microscopic observation of microstructures of an Al-B alloy shows that high viscosity of the molten alloy is due to the formation of a net structure of the AlB2 crystal. The net structure is broken by the K2TiF6 flux treatment and the fluidity of the molten alloy is improved. The reaction mechanism is discussed for the process of producing aluminum boride, the subsequent destruction of the net structure by the K2TiF6 treatment and the formation of the AlB2 crystal.
