Patent DE-3939613-A1 (DE)
Inventor: MILLS DAVID
IPC: B22C1/16
Filed: 1989-11-30
Abstract: Refractory shell moulds are used in the investment casting of superalloys into eg. blades for gas turbine engines. Changes in the superalloys which have been instigated by the need for gas turbine engines to run hotter, have resulted in the forming of superalloys which have melting points which are higher than known refractory shells can withstand. 100% Silica shells have been tried but have low expansion rates and poor green strength. The invention provides a slurry with which an investment casting mould is made, comprising a mixture of zirconium silicate and a first particulate alumina bound by a hydrolised ethyl silicate, and when covering a wax pattern, covered by a further sprinkled particulate alumina of coarser mesh than the first particulate alumina.
