DTA-TG and XRD Study on the Reaction Between ZrOCl2.8H(2)O and (NH4)(2)HPO4 for Synthesis of ZrP2O7
Original language description
In this paper, we report results of thermoanalytical investigation on the reaction between ZrOCl2 center dot 8H(2)O and (NH4)(2)HPO4 in molar ratio 1:2. Differential thermal-thermogravimetric and X-ray diffraction analyses were performed in order to reveal the chemical transformations, which took place during heating of the individual compounds ZrOCl2 center dot 8H(2)O, (NH4)(2)HPO4 and the mixture ZrOCl2 center dot 8H(2)O:2(NH4)(2)HPO4. It was shown that the transformations in the mixture below 160 A degrees C were connected with dehydration of ZrOCl2 center dot 8H(2)O and interaction between the components of the mixture, which resulted in the formation of NH4Cl, NH4H2PO4 and a mainly amorphous zirconium phase, most likely t-ZrO2. The zirconium component subsequently reacted with ammonium dihydrophosphate (below 200 A degrees C) or with dehydrated phosphate derivatives (above 200 A degrees C), which in both cases yielded an amorphous product. The interaction between the components of
