摘要：
The high content of red mud and fly ash glass ceramics was prepared by sintering process, using titanium slag to replace titanium dioxide as Nucleation Agent. The effect of titanium slag content on physicochemical properties, phase composition and microstructure of glass ceramics products were researched mainly. The results show that the main crystalline phase is gehlenite, and the secondary crystalline phase is hedenbergite and anorthite. The crystallinity increases with titanium slag content, but the titanium slag content is high, the crystal will occur condensation phenomenon. When titanium slag content is 6.6%, the compressive strength, flexural strength, microhardness, acid resistance, alkali resistance is 89.43, 53.13 MPa, 6.62 GPa, 0.041%, 0.15%, respectively. Product performance is meet standard of JC/T 872-2000 with building decoration glass-ceramics. ©, 2015, Journal of Functional Materials. All right reserved.
