Abstract

The effect of mechanical activation on the crystallization of glasses of the system SiO2-Fe2O3-BaO-Al2O3 is investigated. The ceramic-glasses are synthesized from silica and iron-rich Ferro-Titanium-Zirconiferous (FTZ) sands available in the state of Coahuila, Mexico. The parent glass is subjected to mechanical activation in a high-energy attrition mill during 4 or 8h. Then, both milled and non-milled glasses are subjected to a thermal crystallization treatment at temperatures of 900 or 1000ºC during 2 or 5h. It is found that, in the case of the thermal treatment carried out at 900°C/5h, an increment in the time employed for both the mechanical activation and the crystallization treatment enhanced the crystallization of the parent glasses and produced an increase in the compressive strength of the synthesized glass-ceramics.
