The Effects of TiO₂ Addition on the Crystallization of Molybdenum Slag Glass

Abstract:

The glass ceramics were prepared by using molybdenum slag (90wt% added) as the raw materials, in which TiO₂ functioned as the nucleation agent. The effect of TiO₂ additions on the crystallization was studied. The crystallization process was investigated by DTA, XRD and SEM. It was showed that TiO₂ can effectively promote the glass formation when the content of TiO₂ is 5wt %. The activation energy for crystal growth E=280.46kJ/mol was evaluated by DTA and kinetic method. The glass ceramic has good properties with main crystal phase of wollastonite.
