Because of the suspected decomposition of anhydrite, CaSO4, in lithium-based tetraborate flux systems at elevated temperatures, it was decided to study their behavior by means of thennal analysis (TGA, DTA). Thermal scans were performed on the Mettler TA-2 thermoanalyzer equipped with a DTA-20 macroholder. Platinum crucibles were filled with 200 mg of specimen flux mixtures and balanced by equal portions of alumina as the reference material. All specimens were heated at a rate of 10 C/min in an oxidation atmosphere (stream of air). 

Few definitive thermal studies of metal-containing polymers (with the exception of silicon-containing polymers) exist in the literature. Thermal analysis is typically done as a matter of preliminary testing on new polymers. Further, most of the studies were done prior to the advent of the automatic, programmed thennal analysis instruments.
