Abstract

Density of liquid CaO-SiO₂-Al₂O₃ system and its structure modification with increasing Al₂O₃ content was studied at a fixed ratio of CaO/SiO₂=1.3. For this investigation, density of the liquid oxides was investigated in the temperature range of 2023 to 2423 K using the aerodynamic levitation technique. The Raman spectroscopy technique was used to understand the structural modification of the quenched oxides with increasing Al₂O₃ content. The density of all the prepared samples decreases with increasing temperature. With increasing Al₂O₃ content, density decreases up to 19.79 mole% and increases with further increase of Al₂O₃ due to Al³⁺ ion role as network modifier.
