Abstract (en)

[origin: WO2013029980A1] The invention relates to a process for producing refractory ceramics (K) for use as heat shield in the hot gas path of gas turbine plants, which comprises the steps: ° - introduction of a casting composition into a component casting mould for the refractory ceramic (K), ° - closing of the casting mould so that the casting composition is under a defined static pressure after closure, ° - oriented vibration of the casting mould in the direction (V) of a normal (N) to a surface of the refractory ceramic (K) to be produced, which is required to meet particular quality requirements for use as heat shield, and ° - subsequent removal from the mould and firing of the cast component.
