Abstract

Sequential thermal transformations of a 3[Pd(NH3)4]Cl2–2(NH4)2Cr2O7 mixture (Pd : Cr molar ratio, 3 : 4) are studied via thermal analysis and mass spectrometry in an argon atmosphere and the temperature range of 50 to 550°C. XRD and elemental analysis show that the solid product obtained after thermolysis of the mixture under the selected conditions is a Pd1 − xCrx palladium-based solid solution that is isostructural to Pd (cell parameter a = 3.8921(5) Å) and the Cr2O3 oxide phase. A model of the solid-phase transformations in the mixture in an argon atmosphere is proposed that includes the formation of palladium and chromium metallic phases.
