Abstract
The present study was aimed at investigating the effect of Na2O and B2O3 addition on the viscosity and electrical conductivity of slag which was used for mineral wool production. Industrial slag samples of the CaO–Al2O3–MgO–SiO2 system were used to modify its composition with different Na2O and B2O3 addition content and soaked at a certain temperature range (1400–1500°C). Raman spectrum was used to represent the structure of the slag system. Results showed that the Na2O addition modified process had a larger effect on the two parameters (macro aspect) and the relative fraction of the structural units (micro aspect) compared with the results of B2O3 addition.
