Abstract | Determination of β′-sialon compositions in multi-phase specimens reacted at 1715°C has been carried out using careful lattice parameter measurements. When all three of the β′-, O′- and X-phases were present, the β′-sialon composition was found to have a consistent z value of 1.1, but no corresponding tie-point was found for overall compositions below the β′ solid solution. This behaviour, coupled with the lack of a reasonable crystallographic explanation, indicated that the β′ tie-point arises from a thermodynamic stability only in conjunction with the O′- and X- phases. © 1997 Trans Tech Publications. |
