- Abstract
- The quantitative structural information such as the relative abundance of silicate discrete anions (Q (n) units) and the concentration of three types of oxygens, viz. free-, bridging- and nonbridging oxygen can be obtained from micro-Raman spectra of the quenched CaO-SiO2-MgO glass samples. Various transport properties such as viscosity, density, and electrical conductivity can be expected as a simple linear function of "ln (Q(3)/Q(2))," indicating that these physical properties are strongly dependent on a degree of polymerization of silicate melts. The methodology outlined in the current study can be extended to predict the physicochemical properties of silicate melts in ferrous and non-ferrous metallurgical processes.
