- Title
Simple Approximate Analytical Solution for Nonisothermal Single-Step Transformations: Kinetic Analysis.
- Authors
Farjas, J.; Roura, P.
- Abstract
The article discusses the development of a technique for approximating the solution for making single-step solid state transformations during nonisothermic conditions. The technique has been used in numerous reaction models and was able to find simple analytical expressions of the transformation rate peaks. After thermal analysis, most solid phase transformations were found to take place in a specific temperature range. The rate constant for the technique was found to follow Arrhenius dependence, and the conclusion was tested on experimental crystallization curves in amorphous silicon and decomposition of calcium carbonate.
