Mass balance at partial run of quartzite carbothermal reduction

J. Węgrzyn ; Silesian University of Technology, Faculty of Materials Engineering and Metallurgy, Katowice, Poland

Sažetak

Mass balance for the process of incomplete carbothermal reduction of SiO₂ to SiC thermogravimetric studies was presented. Tests were performed for the molar ratio of C/SiO₂ = 3 at a temperature of 1 500 °C under an argon flow in the range from 0,1 to 3,4 dm3/min. Mass balance includes the loss due to escape of SiO and the mass of reactants C and SiO₂ due to stopping the reaction. The weight gain of Al₂O₃ crucible was found and also the formation of crust layer on the surface of the samples. The crucible weight gain and the weight of crust layer created were taken into account in mass balance.
