Thermogravimetric Study of Gadolinium Chlorotungstate in Air Between 25 and 1500°C.

Key Points

Gadolinium tungstate exhibited thermal stability up to 710°C, indicating it can withstand high temperatures without major changes.
Two significant decomposition ranges were identified between 710-900°C and 900-1130°C, leading to different products.
Thermal analysis techniques, including DTA and X-ray powder diffraction, were employed to analyze the thermal behavior and composition changes.
Understanding the decomposition behavior of gadolinium tungstate may inform its applications in high-temperature settings.

Abstract

Using DTA, X-ray powder diffraction, chemical and optical methods, the thermostability of Gd3WO6Cl3 was investigated. The compound was relatively stable on heating in air up to 710oC. Above this temperature it exhibited two decomposition temperature ranges (710-900oC and 900-1130oC). The final product consisted of a mixture of gadolinium tungstate of different composition. This suggests the decomposition scheme of polyphase products
