Abstract
Determination of the phase relationships on the join by the quench method has enabled the previously designated “gamma zinc phosphate” to be identified as a solid solution of zinc orthophosphate in magnesium orthophosphate. takes 95 mole % into solid solution at 1000°C. takes a small amount of into solid solution (about 3 mole % at 1000°) and, in order to satisfy the requirements of the Phase Rule, must take a small amount of into solution. The previously determined relationships are discussed in terms of the new data for the zinc‐magnesium orthorphosphate system. Solid solution relationships in the system are diagrammed and discussed.
