What is Microstructural Characterization and Physical Properties of a Slag-based Glass-ceramic Crystallized at 950 and 1100 °C about?

## Glass-ceramic materials were developed from Turkish blast-furnace slags mixed with 3 and 5 wt% titania (TiOz). On the basis of the DTA and the dilatometry analyses, nucleation experiments were carried out at 725°C and crystallization was performed at 950 and at 1100°C. DTA and X-ray dtffraction studies conducted on the glass samples devitrtfied at 950°C revealed glassy regions and small amounts of gehlenite (CazAlzSi07) and merwinite (Ca3MgSizOs) phases whereas complete transformation to melilite solid solution of akermanite ( CazMgSiz07) and gehlenite phases occurred for those crystallized at 1100°C. Optical microscopy and SEM investigations on the slag glass-ceramic crystallized at 950°C revealed large crystals due to surface crystallization whereas bulk crystallization was evident for those crystallized at 1100°C. For both cases, the crystalline size decreased with increasing nucleant content. Wear, hardness, fracture toughness and bending properties of the slag based glass-ceramic material were enhanced with the increase in nucleant content and the crystallization temperature. 0 1997 Elsevier Science Limited. and development work has been conducted in the exploitation of sla
