Method for direct melt synthesis of intermetallic compounds
Abstract
Abstract METHOD AND APPARATUS FOR THE MELT SYNTHESIS OF GROUP III-V, MIXED III-V, II-VI, II-IV-VI AND II-III-V COMPOUNDS, AT LEAST ONE OF THE COMPONENTS FORMING THE COMPOUNDS BEING HIGHLY VOLATILE UNDER THE CONDITIONS OF SYNTHESIS. THE METAL COMPONENTS ARE PLACED IN A REACTION VESSEL WHICH IS SEALED BY A LIQUID SELANT IN COMBINATION WITH A MECHANICAL SEAL PRIOR TO HEATING THE REACTANTS TO A TEMPERATURE AT WHICH ONE OR MORE OF THE REACTANTS DEVELOPS AN APPRECIABLE VAPOR PRESSURE. THE ATMOSPHERE SURROUNDING THE REACTION VESSEL IS PRESSURIZED TO A PRESSURE ABOVE THE MAXIMUM VAPOR PRESSURE DEVELOPED BY THE REACTANTS DURING THE MELT SYNTHESIS WHICH IS ACCOMPLISHED BY HEATING THE REACTANTS. THE COMBINATION OF MECHANICAL AND LIQUID SEAL IS OF A CHARACTER TO PERMIT DIFFUSION BY HIGH-PRESSURE GAS THROUGH IT.
