Pyrolysis study of hydrophobic tholins By TG-MS, TG, DTA and DSC methods
Journal of Thermal Analysis and Calorimetry, 2012This study presents the thermogravimetry (TG) of hydrophobic tholins, obtained from different simulation experiments of prebiotic synthesis carried out in a CH4/N2/H2 atmosphere with spark discharge activation of aqueous aerosols and liquid water. Differential thermal analysis and differential scanning calorimetry were also used to evaluate the thermal

Kinetic study of solid-solid reactions by DTA method (BaCl2 - KNO3 system)
Thermochimica Acta, 1988Abstract The kinetic io parameters of the reaction BaCl 2 +2KNO 3 → Ba(NO 3 ) 2 + 2KCl have been evaluated by the DTA method. The crystalline phases of the reaction mixture have been identified using the X-Ray diffraction method.

Quantitative Phase Analysis in the System CaSO4.xH2O by TG-DTA Methods
1980The quantitative determination of different components in the system CaSO4.xH2O is necessary for the production and application of technical plaster qualities. Applying the common method this analysis needs four divergently prepared samples and a period of about 200 hours. Using a simultaneous TG-DTA apparatus with water vapour atmosphere on the sample,

Thermal characterization of HCN polymers by TG–MS, TG, DTA and DSC methods
Polymer Degradation and Stability, 2011Abstract This paper presents a thermogravimetry (TG) study of hydrogen cyanide polymers, synthesized from the reaction of equimolar aqueous solutions of sodium cyanide and ammonium chloride. Differential thermal analysis (DTA) and differential scanning calorimetry (DSC) were also used to evaluate the thermal behaviour of these black polymers, which ...

Interaction analysis of systems involving refractory compounds by means of DTA method
Thermochimica Acta, 1985Using DTA and other methods, the study on interaction of silicon nitride with nitrides of titanium, vanadium and zirconium carbide was carried out. The typical features of such interactions are the effect of Si3N4 dissociation stability and the formation of transient metals'-silicides.

High-pressure DTA method for clay analysis
1990A technique for differential thermal analysis at pressures up to 10 kbar and temperatures to 950°C in both open and closed systems is presented. Adding a pressure dimension to conventional differential thermal analysis expands the range and type of potential studies significantly.

A New Isothermal DTA Method for the Study of Surfactants at Liquid Surfaces
1980A new isothermal DTA method for the detection and study of surfactants at the liquid/vapour interface is presented, In this method a certain mass of liquid is slightly superheated above its boiling point in two identical vessels by a constant heat input.
