Effect of CaO/MgO Mass Ratio on Phases and Properties of Glass-Ceramics Prepared from Granite Tailings

Abstract

Abstract: The R₂O-CaO-MgO-Al₂O₃-SiO₂ building glass-ceramics have been synthesized by the method of monolithic crystallization. The granite tailings (mass fraction: 56%), TiO₂, and Na₂SiF₆ were used as the main raw material, main nucleating agent, and flux and nucleating agent, respectively. The effect of CaO/MgO mass ratio on the crystallization capacity, crystal phase composition, microstructure and properties of glass-ceramics were investigated. The results show that the increase of CaO/MgO mass ratio is beneficial to the crystallization of parent glasses. When the CaO/MgO mass ratio is lower than 0.88, the main crystalline phases of glass-ceramics are anorthite and hornblende, otherwise, the main crystallize phase transforms into anorthite. Based on the results of XRD, the diffraction peak of anorthite become stronger with CaO/MgO mass ratio increasing. Besides, with the increase of CaO/MgO mass ratio, the number of crystals and grain size gradually increased, the volume density and microhardness increase first and then decrease. When the mass ratio of CaO/MgO is 0.57, the volume density has a maximum value of 2.752 5 g/cm³. Furthermore, the microhardness reaches the maximum value of 8.6 GPa as the CaO/MgO mass ratio is 0.71.
