Applicability of Quasi Steady State Solutions for the Kinetics of Diffusion Controlled Solid State Reactions

摘要: The exact solutions for many diffusion controlled processes are often complex, and alternative numerical methods also far from trivial; this includes powder reactions other solid state reactions. Simpler approximate thus widely used, the most common based on steady or quasi concentration profiles. These usually require fewer independent parameters than accurate solutions, easier to use fitting experimental results.
