KINETICS OF SOLID STATE REACTIONS: SOFTWARE APPROACH AND APPLICATION

Abstract

Countless inorganic, organic and polymeric materials are in the form of solids. Understanding and controlling the mechanism of the solid-state degradation or solid/gas reactions is crucial for designing reactions for new contemporary materials. For such systems kinetics of solid state reactions is very applicable since it explains the mechanism of the thermally stimulated processes and gives information on thermal decomposition, phase transformations, crystallization etc., important for the optimization of the chemical processes. Using useful tool called kinetic triplet (KT): activation energy (Ea), pre-exponential factor (A) and reaction model (f (α)), obtained by Kinetics2015 software package, we get valuable insight into physico- chemical significance of results. The Kinetics2015 software program supports thermal analysis methods (TGA, DTA and DSC) and works in non-isothermal conditions. The presentation will cover wide range of different materials starting from metallic nanocomposites, through polymers and pharmaceuticals for which by using software approach we get information regarding thermal stability and their decomposition. A special case study of thermal degradation of catalyst copper oxide yielding to copper will be discussed in paper in details.
