Most workers in thermal analysis are undoubtedly aware that Perkin-Elmer has been the exclusive manufacturer of thermal null Differential Scanning Calorimeters, which embody our patented power compensation principle, since 1963. Because of their unique construction and operating principle, thermal null DSC’s inherently have unprecedented calorimetric ...

Journal of Thermal Analysis, 1973
In the lectures of this symposium and in the literature too, there is a gap between good theoretical work, based on the assumption of idealized conditions, and good experimental work, with difficulties in the estimation of kinetic parameters. In DTA there are a' number of theoretical models for kinetic interpretation of curves (theories of Borchard and

Quantitative Determinations by DTA
1974In the quantitative determination of minerals the problem is (after Arens) to find out a relation between any measurable DTA effect and an adequate quantity of a mineral in the heated sample being responsible for this effect. Orcel, Agafonoff and Orcel and Caillere have compared the appearence and the temperature of dehydration reactions of unknown ...

Serpentinit (hadec) - nerudna surovina - hornina, ktorej majoritnou zloškou je MgO a SiO2. Tieto dva priemyselne vyznamne oxidy su viazane v roznych formach a v zavislosti na type štruktury su charakterizovane dve podskupinychrizotilu a antigoritu. Pre určenie hraničnej teploty kalcinacie bola použita termicka analyza serpentinitu so zrnitostou pod 200

Many crystalline substances show at distinct temperatures spontaneous, reversible structural transformations, the existence and temperatures of which can be observed very clearly in a DTA curve. However, the nature of the resulting products of reaction remains obscure, since these transformations receded during cooling.
