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.
