Abstract
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° C., optionally mixed with elements having melting points greater than 1000° 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.

Claim 1
Independent Claim
141 words
An apparatus for the vaporization of high-melting point inorganic compositions by means of a photon-generating thermal source of radiation heat in a continuously operated vacum vaporization apparatus which comprises: compacted vaporizable material in the form of a shaped body having an interior portion prepared from at least one pulverulent inorganic composition having a melting point greater than 1000° C. or a mixture of at least one pulverulent inorganic composition having a melting point greater than 1000° C. and at least one pulverulent element having a melting point greater than 1000° C.; a thermal source of radiation heat, coupled without contact, to said interior portion of said compacted shaped body of vaporizable material; and means to move at least one of said shaped body and said thermal source of radiation heat in relation to each other while the body is being heated.
Claim 2
Independent Claim
141 words
An apparatus for the vaporization of high-melting point inorganic compositions by means of a photon-generating thermal source of radiation heat in a continuously operated vacum vaporization apparatus which comprises: compacted vaporizable material in the form of a shaped body having an interior portion prepared from at least one pulverulent inorganic composition having a melting point greater than 1000° C. or a mixture of at least one pulverulent inorganic composition having a melting point greater than 1000° C. and at least one pulverulent element having a melting point greater than 1000° C.; a thermal source of radiation heat, coupled without contact, to said interior portion of said compacted shaped body of vaporizable material; and means to move at least one of said shaped body and said thermal source of radiation heat in relation to each other while the body is being heated.
Claim 3
Dependent Claim
20 words
