    Abstract: An object of the present invention is to provide silica glass having high purity, high heat resistance, large coefficient of thermal expansion, and low light transmittanc. Another object of the present invention is to provide a silica glass jig with a vapor-deposited film thereon. Therfore Cristobalite-contained silica glass wherein α-cristobalite in the shape of a small sphere or a small, round-edged or sharp-edged, three-dimensional region is dispersed in the silica glass matrix, the diameter of each α-cristobalite sphere or region is in the range of 0.1 µm to 1000 µm, a content of the α-cristobalite is at least 10 wt %, and small-sized independent bubbles which are additionally dispersed in the silica glass matrix. The silica glass jig is made of the cristobalite-contained silica glass and the surface of the jig is covered with a vapor-deposited thin film which has a property of being resistant to plasma etching, and which is made of a material of almost the same coefficient of thermal expansion as that of the silica glass. The silica glass jig has no chance to generate particles therefrom and thereby to contaminate a silicon wafer.

    Abstract: The invention relates to a method for the production of opaque quartz glass wherein a blank is made from synthetic SiO2 crystals and heated to form a blank body made of opaque quartz glass at a given vitrification temperature. A method for the production of pure, opaque quartz glass is disclosed wherein said quartz glass has a homogeneous pore distribution and a high density, a high viscosity and a lower tendency to devitrify. According to the invention, the SiO2 crystals are formed from an at least partially porous agglomerate of SiO2 primary particles (21; 31) having a specific surface (according to BET) between 1.5 m /g and 40 m /g with a stamping density of at least 0.8 g/cm . SiO2 granulate (21; 31) suitable for use in performing the procedure is characterized in that it is composed of an at least partially porous agglomerate of SiO2 primary particles and has a specific surface (according to BET) between 1.5 m /g and 40 m /g in addition to a stamping density of at least 0.6 g/cm .
