Heat-insulation material and arrangement of a heat-insulation layer containing said heat-insulation material

摘要

A heat-insulation material for a heat-insulation layer ( 3 ) for a carrier body ( 2 ) for preventing heat transfer between the carrier body and a surrounding area ( 7 ) therearound includes at least one luminous substance which is excitable for emitting luminescent light having a defined emission wavelength and includes at least one type of metal oxide containing at least one trivalent metal (A). Also described is an arrangement of at least one heat-insulation layer which contains the heat-insulation material and is applied to the carrier body. The described heat-insulation material is characterised in that the metal oxide is embodied in the form of a mixed oxide selected in a perovskite group of total formula AA'O₃, and/or of pyrochlore of total formula A₂B₂O₇, wherein A' is the trivalent metal and B is a tetravalent metal. The heat-insulation layer containing the heat-insulation material is preferably used for a gas turbine.
