High Temperature Proccesses

Welcome to the "High Temperature Processes” course. Within the framework of this course, concepts such as the following will be presented: high temperatures measurement, thermodynamics and phase equilibrium, glass, cement, traditional ceramics, diffusion and methods for determining diffusion coefficients, nucleation, sintering and high temperature fuel cells. This course is taught in the School of Chemical Engineering at the National Technical University of Athens. The webpage of the course at the Faculty is: http://www.chemeng.ntua.gr/the_course/High_Temperature_Proccesses.

Objectives

The main aims of the course "High Temperature Processes" of the 8th semester are the description of the physicochemical changes during processing of materials at high temperatures, the study of changes in the structure and properties as well as relevant case studies.

Prerequisites

For this course knowledge of inorganic chemistry, physico-chemistry and thermodynamics is required.
