ABSTRACT:
A method of manufacturing glass or ceramic bodies in which an open-pore green body is formed from the starting material which is subjected to a purification process in a heated purification gas reacting with impurities present in the green body in such a manner that the device in which the green body to be purified is present is rinsed with flowing purification gas, is then sealed and subsequently evacuated until the gases present in the open-pore green bodies in the form of purification gas and gaseous reaction products have been removed, after which the purified green body is sintered, in which metallic impurities in the form of elements of the groups Ib, Va, VIa, VIIa, and/or VIII of the Periodic Table of Elements are converted into volatile complex compounds by a purification gas consisting of a carrier gas saturated with a sulphur-oxygen-halogen compound at a temperature in the range from 200.degree. to 500.degree. C.
