Ceramic element or ceramic layer having high porosity, their use and ceramic element comprising said layer

摘要

The ceramic massive component or ceramic layer useful for the application at high temperature of >= 1200[deg] C for the component of steam turbine or gas turbine, where the massive component or ceramic layer has a porosity of 26 vol.%, a hardness of 630 HV(0.3), a pore cross-section of 9000-12000 mu m 2>, and a layer thickness of greater than 1500 mu m, is claimed. An independent claim is included for a component such as steam turbine or gas turbine.
