Phase relations and interfacial reactions in the Ga-P-Co system at 500 °C


The isothermal cross section through the ternary phase diagram Ga-P-Co at 500 °C was constructed. No ternary phases exist in the system at this temperature. All binary Co-P and Co-Ga intermetallics are in equilibrium with GaP, which, under these conditions, dissolves up to 4 at.% of cobalt. The use of equilibrium phase diagram information in predicting the variation of chemical composition in the diffusion zone during solid-state reaction between GaP and Co is demonstrated.
