COATED COMPONENT CONSISTING OF QUARTZ GLASS, AND METHOD FOR PRODUCING SAID COMPONENT

摘要

The invention relates to methods for producing a coated component consisting of quartz glass, according to which the component surface is at least partially provided with a SiO2 glass composition that differs from the quartz glass of the base body. The aim of the invention is to provide a novel way of coating a quartz glass component with a SiO2 glass composition that can be produced in a cost-effective, reproducible manner, with any thickness, and can fulfil various functions according to the concrete embodiment thereof. To this end, an amorphous slip containing SiO2 particles is produced and applied to the surface of the base body, forming a slip layer which is dried and then vitrified, forming a SiO2 glass composition. The quartz glass components coated in this way can be advantageously used especially in the production of semiconductors.
