By introducing other raw materials(SiO2, Al2O3, CaO) into the red mud ,all above materials were melted into Fe2O3-CaO-Al2O3-SiO2 system glasses.On the basis of 17.2Fe2O3-5.7CaO-18.2Al2O3-50SiO2-5.9Na2O-3TiO2 system glasses, [Al2O3] / [CaO] mass ratio changed further.For each sample, the assignment of IR absorption bands for FCAS system glasses were investigated by Fourier Transform Infrared Spectroscopy and the glass-transition temperature and high temperature molten state studied by Differential Scanning Calorimetry.
