Differential thermal analysis oxide minerals

The technique of differential thermal analysis (D.T.A.) has been extensively employed in the study of clay and other minerals for elucidating their structures for more than three decades. The application of D.T.A. as a tool has not been widely made to the systematic study of solid catalysts. Only a few references on the subject could be foimd 1-6). In the present article, differential thermal studies of a number of solid catalysts like chromic oxide gels, ferric oxide gels, and chromic oxide-ferric oxide are reported. An attempt has also been made to correlate the data with x-ray... 

Very little further progress in instrumentation was made until the 1950s. By 1952 approximately 1,000 research reports on differential thermal analysis had been published. DTA was mainly used to determine phase diagrams, transition temperatures, and chemical reactions, as well as for qualitative analysis of metals, oxides, salts, ceramics, glasses, minerals, soils, and foods.
