Topic description and teaching suggestions: This topic encompasses various aspects and applications of high temperature processing in particular of individual metallic and alloys systems and also ceramic systems: reactions involving solids, metal extraction processes through carbothermal and metallothermal reduction of oxide minerals, metal refining processes through gas-solid reactions (e.g. chlorination and fluorination reactions of simple and mixed oxides), degradation of materials etc. Pyrometallurgical treatments of materials (purification, recovery of metals, etc.) are commonly employed in nuclear reactor technology. Basic knowledge of physico-chemical aspects of pyrometallurgy provide students of chemistry, industrial chemistry, materials science oriented to metallurgy and those concerned with the science of metal-making and refining at high temperatures, with the information to understand how processes of industrial importance work and possibly, how to improve them. A prerequisite is a basic knowledge of thermodynamics and kinetics. The teacher may select and illustrate some examples like the chlorination reactions of metal oxides and the vapor phase refining and separation of metals (relate this topic with the vapor transport reactions dealt with separately; see section 9.2.a).
