Processing of mineral and technogeneous raw materials by carbothermal reduction

Current studies dealing with the preparation of promising materials (most of all, ceramics) by carbothermal reduction (CR) of mineral and technogeneous raw materials is surveyed. Attention is concentrated on the mechanisms and kinetics of chemical reactions occurring during the CR process and on the effects of varying some factors during the reduction (temperature, duration of annealing, composition of the gas phase, ratio of the components, density of the blend,etc.) on the compositions and properties of the final products. Ways of optimizing particular technological schemes for the production of new materials by the CR method are discussed. Deceased. Translated fromIzvestiya Akademii Nauk.
