Aims

The aim of the course is to acquaint students with the basics of transfer phenomena (momentum sharing, steady and permanent energy and mass sharing) in relation to kinetic heterogeneous processes, synthesis and decomposition, or to reduce costs that can be processed in the production of materials. Acquisition of principles suitable for design and construction of technological units.
The student gains information about the influence of momentum, energy and mass sharing on the speed of processes in condensed systems and creates an image of optimization of conditions for preparation of materials with required technical properties.
Knowledge of mathematical models, which are used to describe processes taking place in bodies of various materials.
Knowledge of the course of isothermal and non-isothermal reactions in heterogeneous systems where substances transfer between phases.
Knowledge of the steps and morphological processes that describe sintering, crystallization, dissolution and phase transformation.
Knowledge of reaction of solids with gases and reaction of two solid phases.
