The most debatable and discrepant viewpoints of non-isothermal kinetics are discussed in the form of twelve questions and answers. The reputation of non-isothermal kinetics when carried out by thermoanalysts; the consequences of simplified concepts transferred from the kinetics of homogeneous reactions; the physical meaning of basic kinetic parameters in solid-state processes; the kinetic compensative effect and interdependence of kinetic parameters using the Arrhenius rate constant; the mutual usefulness of differential and integral methods of kinetic data evaluation; their accuracy and correctness; the reliability of DTA measurements; non-isothermal versus isothermal investigations; equilibrium and kinetic data and their mutual effect; the extended discussion initiated by MacCallum and Tanner; non-isothermal data publication policy; and finally the use of computers.
the PTFE thermal decomposition at different conditions [ 4 ]. In this connection, for an adequate design and/or operation of the equipment involved in the recycling of PTFE by decomposition processes it is necessary to known the kinetics of the

requirement of high cooling rates is fulfilled by this type of glass preparation. The crucial factor of preparation of these progressive materials in glassy form is the crystallization kinetics [ 3 – 8 ].
The crystallization kinetics of two binary
In examining past Forest Products Laboratory (FPL) research on wood pyrolysis kinetics, it is chosen as the starting point the confluence of technologies achieved with thermal analysis (TG, DSC, and gas
The application of thermal analysis in the study of reaction kinetics and reaction mechanisms in combination with presently available powerful analytical tools, in the sphere of materials with particular reference to high energy materials is presented and discussed. Also an attempt has been made to correlate the kinetic data obtained by TA with the performance characteristics, for some important materials.
Non-isothermal thermogravimetric analysis was used for determination of the kinetics of aluminium hydroxide dehydration in an air atmosphere and for processing of the experimental results by the method due to Chatterjee.
semiconducting chalcogenide glasses is crucial to understand their properties and functions. In fact, the understanding of glass transition kinetics of chalcogenide glasses aims at establishing their thermal stability and glass-forming ability (GFA). This enables
