Abstract

Abstract

The glass-ceramics were prepared by sintering method from an iron tailings in Shangluo area. The optimum process parameters of melting base glass were optimized. The effects of the crystallization temperature on the compressive strength, density and thermal expansivity of glass-ceramics were investigated. The results show that optimal performance of the base glass melted can be obtained at the melting temperature of 1400℃ and melting time of 2 h. Moreover the best properties of the glass-ceramics such as compressive strength of 158.32 MPa, density of 2.74 g/cm³, thermal expansivity of 6.8×10^-6K^-1 could be obtained at the crystallization temperature of 900℃ and holding time of 2 h.
