Quartz glass component and method for the production thereof

摘要

Disclosed is a component made of quartz glass, especially a crucible. A blank is provided with a stabilizing layer exhibiting a higher softening temperature than quartz glass. In order to provide a quartz glass component which is characterized by high mechanical and thermal resistance, in addition to providing a simple, cost-effective method for the production of said component, the chemical composition of the stabilizing layer (3; 6; 7; 38) is different from that of the quartz glass and said layer is applied by means of heat injection. The inventive method is characterized in that a stabilizing layer (3; 6; 7; 38) whose chemical composition is different from that of quartz glass is applied by heat injection.
