Synthesis of Glass Ceramic from Goldmine Tailings

Abstract:

Article Preview

Glass ceramic was successfully synthesized using goldmine tailings as main raw material. The frit preparation and molding techniques, and the nucleation and crystallization processes were discussed. The results showed that only one crystalline phase, idiomorphic diopside, was formed in shapes of small columns and grains. The optimum temperatures for melt, sintering, nucleation and crystallization were 1350°C, 1160°C,750°C,and 860°C, respectively.
