Abstract

This article describes the major factors affecting the process metallothermy and determine the possibility of their implementation (the value of the specific heat effect and the process temperature). Aluminothermic reduction of metals from their oxides may be effected without the use of an external heat source. The heat of formation of aluminum oxide at a given temperature is a constant and the final thermal effect aluminothermic reduction depends on the heat of reducible oxides. Determines the temperature of combustion reactants charge materials. The combustion temperature of the exothermic mixture of SiO2-Al measured by a thermocouple way. The calculation of the temperature recovery process silica in the adiabatic mode provided the reaction under standard conditions.
