摘要： In a method of moulding a ceramic core for use in the production of precision equipment separable die parts of resin are formed from a master model and resin oddsides are cast from the die parts. Further die parts formed from the oddsides are faced with nickel by electroforming and the faced die is then used for high speed injection moulding. Required slight changes in shape of the core can be obtained by altering the shape of the cast oddside and then casting new metal faced die parts.

摘要： A profiled body of silicon nitride and aluminium nitride dipped in a silica solution such that the silica infiltrates the pores of the body. This silica, together with unconverted silica present in the body, reacts with the aluminium nitride when the body is subsequently fired at around 1800°C in a controlled atmosphere to form sialon. As all the silica is utilised in the reaction, a sialon is formed which can retain its strength up to around 100,000 p.s.i. and at temperatures above 1000 * C.
Alternatively, the body is infiltrated with alumina to form sialon when fired to at least 1800°C in a controlled atmosphere.
