Physico-chemical study of the Cr₂O₃‑SiO₂ system (to on the problem of finding new highly refractory materials)
- канд. хим. наук
Abstract
The development of modern electrometallurgy raises the question of finding new highly refractory materials that increase the service life and productivity of electric furnaces. The study of the dependence of the melting temperature on the composition of mixtures of highly refractory materials, especially the determination of the areas of formation of solid solutions with high refractoriness, is one of the ways to find highly refractory materials. Among the existing refractories, chromite, magnesite, zirconium dioxide, etc., deserve great attention. At present there are already a number of studied systems of chromium oxide with oxides MgO, CaO, Al₂O₃, ZrO₂. The Cr₂O₃‑SiO₂ system has not been studied yet. Its study was carried out by us in connection with the subsequent study of the ternary system Cr₂O₃‑SiO₂‑ZrO₂, which is not only theoretical but also of practical interest in the search for new highly refractory materials.
