In order to achieve high-value utilization of kaolinite type coal gangue in North China, the circular economy of mining area is developed. This paper reported anorthite glass-ceramics was successfully prepared using the kaolinite type coal gangue from Xiegou colliery of Shanxi Province by the sintering process. The effect of different TiO2 content on the crystallization behavior and the performance of the final prepared glass-ceramics was studied by the methods of X-ray photoelectron spectroscopy, X-ray diffraction, differential scanning calorimetry, physical properties test, etc. The results show that the crystallization temperature of anorthite glass-ceramics decreases from 979.3 ℃ to 915.8 ℃ with the mass fraction TiO2 increase from 1.09% to 7.09%, and the main crystalline phase can always keep with anorthite, suggesting the TiO2 content increase reduces the crystallization temperature without change the main crystalline phase. The appropriate addition of TiO2 can promote the generation of crystal nuclei and increase the number of grains significantly, and the single crystal particles become fine, thus increasing the compactness of glass-ceramics and improving its physical and chemical properties. The glass-ceramics obtained after nucleation at 800 ℃ for 2 h and crystallization at 1 025 ℃ for 2 h with TiO2 content of 5.09% have excellent physical and chemical properties, with bulk density of 2.88 g·cm-3, acid resistance of 97.93%, alkali resistance of 99.98%, and flexural strength of 124.5 MPa. The prepared glass-ceramics have excellent performance and good application prospect.
