Abstract
Apparatus for the melt synthesis of inorganic compounds from elemental reactants, at least one of which is highly volatile at the temperature of the reaction. An enclosure means defining a reaction chamber and a reservoir-closure means containing the volatile elemental reactant form the reaction vessel which is sealed by a combination mechanical-liquid seal which is of a character to permit diffusion by high-pressure gas through it. Heating means are provided to effect at least three heating regimes: (I) liquefaction of a liquid sealant, (II) formation and maintenance of a molten reaction mass, and (III) heating of the volatile elemental reactant to vaporize it.
