Thermal stability of the Pr3Pt4 compound

The temperature stability of the Pr3Pt4 compound was investigated by isothermal annealing at different temperatures, X-ray diffraction (XRD) and differential thermal analysis (DTA). It was found that the decomposition reaction Pr3Pt4 - > PrPt + PrPt2 took place at temperatures ranging approximate...

More Information
Summary:The temperature stability of the Pr3Pt4 compound was investigated by isothermal annealing at different temperatures, X-ray diffraction (XRD) and differential thermal analysis (DTA). It was found that the decomposition reaction Pr3Pt4 - > PrPt + PrPt2 took place at temperatures ranging approximately from 360DGC to 830DGC and it was an exothermal reaction. After annealing at 500-750DGC for 7 days, the Pr3Pt4 compound decomposes completely into the two neighboring compounds PrPt and PrPtz.
