Abstract
Methods of thermodynamic analysis and gravimetric measurement are used to study graphite and its mixtures with metal oxides heated to 1000°C under nonisothermal conditions. The chemical compatibility of graphite with Al2O3, CaO, SiO2, MgO, Fe2O3, TiO2, Na2O, and K2O is investigated. It is shown experimentally that under the given conditions the loss of mass (Δm /m) in specimens with these additives as reflected by the gravimetric curves does not exceed Δm /m in a purely graphite specimen.
