    Abstract: To provide a technique with which a quartz glass jig and a doped quartz glass jig are regenerated by completely removing the impurities which are attached to the surface and the impurities which have diffused into the interior from quartz glass jigs which have been used in semiconductor production processes and then carrying out working repair and removing the contamination from the working processes as well. After use, the impurities are removed from the aforementioned quartz glass jigs in the said purification treatment process which includes a purification treatment process in which the quartz glass jigs are subjected to a purification treatment in a gaseous atmosphere which includes a halogen element at a temperature within the region above a prescribed temperature.

    Abstract: A quartz glass lamp vessel 1 or 21 is used in many types of lamps. Sometimes it is expedient to absorb a certain portion of the emission spectrum. In accordance with the prior art this is possible by including rare earth metal oxides in the quartz glass.The solubility of rare earth metal oxides in quartz glass is, however, limited.According to the invention, quartz glass is used which contains an alkali metal oxide and optionally, an alkaline earth metal oxide, in addition to a rare earth metal oxide. The alkali metal oxide increases the solubility of the rare earth metal oxide, so that rare earth metal oxides can be used in larger concentrations. This results in glasses which have a higher degree of absorption, from which lamp vessels can be produced.
