| Abstract | This work provides an effective method for realizing both resource utilization and high-value utilization of bulk industrial solid waste. The influence of non-equilibrium cooling rates on the internal energy and amorphous structure of the precursor glass is studied to clarify the nucleation process of various crystals. A new method is proposed to control the glass formation and crystal growth process by using the cooling rate of the hightemperature melt. Research results show that the crystallization enthalpy (?Hc) of the precursor glass decreases with decreasing cooling rates, and the NBO/T gradually decreases. When the non-equilibrium cooling rate is (k) > 10 ?C/min, ?Hc is ? 157.05 kJ/mol and NBO/T increases to 1.09. Additionally, the glass network structure is unstable and mainly consists of Q4 structural units, which promote canasite-A crystal nucleation. The Cxonotlite:Ccanasite-A ratio increases from 1:1 to 1:5, and the crystallinity increases by 25.49%. The flexural strength of the silicon slag glass-ceramics also increases by 59.19%. |
