ABSTRACT:
An apparatus for the vaporization of inorganic compositions uses a photon-generating thermal source of radiation heat in a continuously operated vacuum vaporization processes. The apparatus includes a shaped body of the compacted vaporizable material prepared from pulverulent inorganic compositions having melting points greater than 1000.degree. C., optionally mixed with elements having melting points greater than 1000.degree. C., and a thermal source of radiation heat, the vaporizable material and a thermal source of radiation heat being coupled without contact. The vaporizable material is constructed as preferably a porous, shaped body and the shaped body and/or the thermal source of radiation heat are movably arranged relative to each other.
