Abstract
Cesium phosphates with different Cs/P molar ratios were prepared by a solution evaporation method. X-ray powder diffraction, thermogravimetric, and differential thermal analyses were performed in order to reveal the chemical transformation and phase compositions which take place during the heating of the mixtures Cs2CO3/(NH4)2HPO4 and CsNO3/(NH4)2HPO4 as well as individual compound. The effects of the Cs/P molar ratio, Cs source and treatment temperature on thermal behavior of the cesium phosphates were investigated. The results showed that different reactions take place with molar ratio from 1/2 to 3/1. Meanwhile, the thermostability of Cs2CO3 and CsNO3 intimately affects the phase composition and phase transition during heating process. However, for all the Cs–P oxides samples, the crystallinity was decreased differently after higher temperature treatment.
