In the prodn., by pressing and sintering, of a dense, high temp. creep resistant, fully crystalline sintered body of a phase isomorphic with beta silicon nitride plus yttrium-aluminium-garnet from a powder mixt. of silicon nitride, yttrium oxide aluminium nitride, silicon dioxide, promoter for crystallisation of the garnet from the sialonic melt, and organic binder, the novelty is that the aluminium nitride: yttrium oxide:silicon dioxide wt. ratio is 0.960+/-0.096:1.337+/-0.134:1. |
