摘要
Composite ceramic material has a substrate made of oxidic fiber materials with SiO2 phases and an oxidic matrix having a graded thermo-chemical protective layer which is free from silicon dioxide on the surface facing away from the substrate and having the same chemical composition as the substrate on the surface facing the substrate. Preferred Features: The oxide fiber material is a fiber bundle, fleece, knitted material and/or woven material. The thermo-chemical protective layer is made from yttrium-stabilized zirconium oxide, cerium-stabilized zirconium oxide and/or yttrium-aluminum garnet.
