Description

technical field [0001] The invention belongs to the field of resource utilization of industrial solid waste, and in particular relates to a composite tailings slag glass-ceramic and a preparation method thereof. Background technique [0002] Glass-ceramics is an ideal high-grade interior, exterior wall and floor decoration material. It is a polycrystalline solid material containing a large number of microcrystalline phases and glass phases obtained by thermal treatment and crystallization of basic glass with a specific composition. It has high mechanical properties. Excellent properties such as strength, good wear resistance and chemical corrosion resistance, extremely low water absorption and expansion rate, and unique optical properties. Traditional glass-ceramics are mainly prepared from natural mineral raw materials, which are expensive. Therefore, the preparation of glass-ceramics from solid wastes has attracted more and more attention. [0003] Electrolytic manganese ...
