Differential thermal analysis (DTA) is complementary to thermogravimetric analysis (TGA). However, DTA is much more versatile. The data obtained from DTA are of more fundamental in nature. In DTA, a smaple and a reference material .Dierential Thermal Analysis 12.1 INTRODUCTION Dierential thermal analysis (DTA) is complementary to thermogravimetric analysis (TGA). However, DTA is much more versatile. The data obtained from DTA are of more fundamental in nature. In DTA, a smaple and a reference material are heated (or cooled) at a linear heating rate.
DTA is the simplest and most widely used thermal analysis technique. The difference in temperature, ∆T, between the sample and a reference material is recorded while both are subjected to the same heating programme.In ‘classical’ DTA instruments, represented schematically in Fig. 4.1, a single block with symmetrical cavities for the sample and reference . This instrument is used for reaction velocity and acceleration degradation tests, as well as analysis of the water and ash content in samples, and evaluation of decomposition, oxidation and heat resistance of samples. Features. As a forerunner in the balance beam mechanism, this instrument utilizes a horizontal differential type balance beam. 3. Differential Thermal Analysis (DTA): • Differential thermal analysis (DTA), in analytical chemistry, a technique for identifying and quantitatively analyzing the chemical composition of substances by observing the thermal behavior of a sample as it is heated. • The technique is based on the fact that as a substance is heated, it undergoes reactions and .A differential thermal analyzer, also commonly referred to as a DTA analyzer, is used in analytical chemistry to identify and quantitatively analyze the chemical compositions of a sample by heating the sample and recording the behavior of the sample, which includes the temperature and heat flow between phase transition (i.e. melting point, crystallization, etc.) as a sample will .
The thermogravimetric and differential thermal analysis of the compound under study is performed to determine the temperature of sublimation and thermal events such as melting. Figure \(\PageIndex{17}\) shows a typical TG/DTA plot for a gallium chalcogenide cubane compound (Figure \(\PageIndex{18}\) ).Differential thermal analysis (DTA)/thermogravimetric analysis (TGA) (DT-60H thermal analyzer, Shimadzu, Japan) changes for magnesium silicate are shown in Fig. 7.13.The data shows an endothermic peak with a maximum at T max = 119 °C resulting in a mass loss of 21.5% of the total weight. This loss continues at a slow rate up to 700 °C to yield another 10.5% mass .

Experimental Methodologies for the Characterization of Nanoparticles. Ashok K. Singh PhD, in Engineered Nanoparticles, 2016 7.2 Differential Thermal Analysis. Differential thermal analysis (DTA) is based on the principle that the substance, upon heating, undergoes reactions and phase changes that involve absorption or emission of heat. The sample to be analyzed is .Abstract: Combined use of thermal analysis techniques can realize complementarity of different characterization methods. Comprehensive thermal analysis with both thermogravimetric analysis and differential thermal analysis (TG/DTA) can measure not only mass change of a sample but also The use of differential thermal analysis (DTA) for estimating calorimetric quantities is dependent on the proper control, calibration, and operation of an instrument designed for quantitative work.
