Abstract: A ceramic heat shield for a gas turbine. The ceramic heat shield has a ceramic body containing aluminium oxide and has a surface layer of the ceramic body which contains yttrium aluminium garnet as reaction coating material. A gas turbine includes such a ceramic heat shield and a method produces such a ceramic heat shield.

Abstract: A ceramic absorber for damping, in particular absorbing, vibrations, in particular combustion vibrations, preferably in gas turbines, which has a foam structure. For the ceramic absorber, the sound absorption capacity is set in a defined way and the efficiency is improved. The foam structure is based on a ceramic powder which contains either a component from the class of silicates or a component from the class of oxides, or a combination of a component from the class of silicates and a component from the class of oxides, and the foam structure has a homogeneous pore distribution.

Abstract: A pressure casting slip for producing a refractory ceramic for use as a heat shield, e.g. in the hot gas path of gas turbine units, includes a particulate mixture of at least two materials having different coefficients of thermal expansion and also organic and/or inorganic binders and floating agents. The particulate mixture has a multimodal particle size distribution divided into 10-20 percent by weight of coarse particles in the size range 1-5 mm in diameter, 10-20 percent by weight of medium particles in the size range 0.5-1 mm in diameter and 60-80 percent by weight of fine particles in the size range up to 0.5 mm in diameter which together make up 100 percent by weight of the particle mixture.
