    Abstract: Moulded bodies made of quartz glass with at least one surface region of tranparent quartz glass, whose free surfaces are smooth and which have a superficial microroughness of less than 8 mu m, are already known. To facilitate production of such a body having a simple structure, cost-effectively and without the need for the stocking or separate production of auxiliary components, it will consist of a core body, the base material of which is at least 99.9 % chemically pure and has a cristobalite content of no more than 1 %; is impermeable to gases, opaque, and porous, has a virtually constant direct spectral transmission in the wavelength range lambda = 190 nm - lambda = 2.650 nm of below 10 % for 1 mm of thickness, and has a density of at least 2.15 g/cm . The transparent surface region is formed from the base material which is heat treated at a temperature in excess of 1.650 DEG C, is at least 0.5 mm thick and has a direct spectral transmission of at least 60 % in the wavelength range lambda = 600 nm - lambda = 2.650 nm for 1 mm of thickness. The invention also relates to process for manufacturing a moulded body of this type from quartz glass.

    Abstract: A method for producing a quartz glass body from a get body is provided, wherein the gel body generated from a colloidal suspension is at least formed and compressed into the quartz glass body Displacement bodies are added to the colloidal suspension prior to gelating into the gel body, and are completely removed from the gel body after gelating, wherein hollow spaces are generated at the positions of the removed displacement bodies, so that a translucent or opaque quartz glass body is generated. Further, a gel body for producing a quartz glass body is provided, wherein displacement bodies are introduced into the gel body that can be completely removed from the gel body, so that hollow spaces arise at the positions of the displacement bodies. A quartz glass body is also provided that includes vacuoles or hollow spaces filled with gas.
