Process for protecting openings in a component during a treatment process, preventing penetration of material, and a ceramic material

摘要

In the process according to the invention for protecting openings in a component made from an electrically conductive base material, in particular from metal or from a metal alloy, during a treatment process, preventing penetration of material, prior to the treatment process the openings are closed up using a filling material which is removed again following the treatment process. The process according to the invention is distinguished by the fact that chains of Si-O-Si and/or Si-O-C are used as filling material.
