Аннотация: The behavior of palladium, rhodium, iridium, and platinum powders during their heating in an argon atmosphere was studied by differential scanning calorimetry (DSC). The DSC curves showed the exothermal peaks corresponding to the enlargement of the platinum group metal powders under study. Electron microscopy and XRD studies revealПоказать полностьюed that the particle size of highly disperse powders changed during the heating. Chemisorbed oxygen was removed from the powder surface above 800 K. During the heating of the mechanical mixture of highly disperse platinum and palladium powders, a solid solution formed with an exothermal effect.
