Several TA methods (including dynamic TA, Q-TA, emanation and special
conductometric TA) were used in investigations of condensed phosphate
synthesis, and in the evaluation and control of the reactivity of the
raw materials, when high-temperature stable pigments are developed. Co
nductometric TA occupies a special position because of its high sensit
ivity to most changes in crystal structure at the beginning of reactio
ns.
