Using Red Mud Manufacturing Building Glass-Ceramics

In this paper, red mud of aluminum industrial residue has been studied to make the glass-ceramic, quartz sand, magnesite, fluorite and red mud was mixed to melt, molten glass was poured into the model in shape, then annealing, glass-ceramic was make, the color of glass-ceramic is brown or black, the crystals in glass-ceramic body is iron oxide by XRD, Strength, the expansion coefficient and morphology of the sample were measured. Glass surface color depends on the melting temperature.
