Thermogravimetric data analysis

MgFe204 spinel calcined at 900°C be deter- mined from the data Can the appearance of spinel peaks at 700°C be approximately correlated to the results from thermogravimetric (DTA) analysis shown in Figure 1 of Ref. 65 ... 

The thermogravimetric (TG) as well as difference thermogravimetric (DTG) analysis data are summarized in Table IV. The thermograms of selected derivatives are presented in Figure 1.

The number of grafted moieties have been calculated from both elemental analysis and thermogravimetric data reported on table 1. 

The presence of the co-ordinated hydroxy-groups was confirmed from i.r. and thermogravimetric data. Oxidative addition of iodine to [Pt(acac)2], either in the solid state or in carbon tetrachloride solution, has yielded the black complex [Pt(acac)2l2]- U.v.-visible and mass spectral measurements show the reaction to be reversible in solution or in the gas phase, and a singlecrystal X-ray analysis (Table 8) indicates trans octahedral geometry for the product. 

The thermogravimetric data obtained for the thermal degradation of ascorbic acid samples are summarized in Tables 3.4 and 3.5. Based on these results, the heating rate of 10°C min was chosen for further analysis. The thermogravimetric data for thermal degradation of ascorbic acid samples at a heating rate of 10°C min in the three studied atmospheres are summarized in Table 3.2. The three thermogravimetric curves are shown in Fig. 3.14.

Spectral analysis of volatile products shows that pure plasticizer evaporates before thermal degradation of PVC is recorded.Kinetic models of PVC thermal decomposition for interpretation of thermogravimetric data were proposed and verified by experimental data. ... 

The cured and the liquid polymers degrade essentially by the same mechanism (see Equation 6.1). The kinetic analysis of the isothermal and dynamic thermogravimetric data of the liquid polysulfide polymer cured with ammonium dichromate is explained by a kinetic model based on random initiation, followed by rapid termination by disproportionation. The average overall activation energy obtained by different methods for the decomposition is 145.3 kj/mole ... 

Although the thermal degradation of a polymer is complex and may involve successive and/or parallel steps, kinetic analysis of thermogravimetric data is...
