Reuse of Spent Foundry Sand in Development of Glass-Ceramic Material with Wollastonite Phase

Spent Foundry Sand is one of the largest industrial solid wastes generated by foundries in production iron and steel components. Currently, millions tons molten sands are discarded worldwide. Therefore, this work aims to reuse for glass-ceramic materials, since minimizes environmental impacts related its discarding. The Sand, composed >60% SiO2, was mixed with limestone melted at 1500 °C produce glass (melting rapid cooling method). materials were characterized X-Ray Fluorescence, Diffraction thermal analysis. results tablets treated 875, 941 1050 show that formed phases Wollastonite-1A, β-Wollastonite Akermanite. In summary, it possible from Wollastonite phase.
