Mathematical models of viscosity diagrams and crystallization temperatures of melts of the CaO – SiO₂ – Al₂ O₃ – B₂ O₃ system

Abstract

Mathematical diagrams of viscosity and crystallization temperatures of melts of the CaO – SiO2 – Al2 O3 – B2 O3 system were created. To obtain them, experimental studies were carried out using the simplex-lattice method of experiment planning. It was used to study 35 slags containing (wt.%) 9.8-52 CaO, 33.6-70.4 SiO2, 16.0-51.52 Al2 O3, 0-20 B2O3. The experiments were carried out on an electrovibrational viscometer in molybdenum equipment, in a stream of purified argon in the temperature range of 1 473–1 923 K.
