Abstract

The invention discloses a method for preparing microcrystalline glass from lead-zinc tailings and quartz tailings. The method comprises the following steps: heating for melting the lead-zinc tailings,the quartz tailings and a modifier to obtain a glass melt, performing water quenching to form glass granules, performing ball milling, drying a slurry obtained during ball milling to obtain a glass powder, spreading on a mould, sintering, crystallizing, annealing, cooling, polishing the surface of a product to obtain a finished microcrystalline glass product. By the method, the comprehensive utilization rate of the lead-zinc tailings and the quartz tailings is high; the preparation method is simple; raw materials are convenient in sources and low in cost; the prepared microcrystalline glass has excellent bending strength and micro hardness and is relatively high in added value; a novel way is provided for comprehensive resource utilization of the lead-zinc tailings and the quartz tailings; the method has significant economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a method for preparing glass-ceramics by using industrial waste slag as a raw material, in particular to a method for preparing glass-ceramics by using lead-zinc tailings and quartz tailings. Background technique [0002] Glass-ceramics, also known as glass-ceramics, is a basic glass with a specific composition added with a crystal nucleating agent (or without a crystal nucleating agent), which is prepared by controlling crystallization during the heating process and contains a large number of microcrystalline phases and Composite material with uniform distribution of glassy phase. Glass-ceramics has the characteristics of no brittleness, high strength, good chemical stability, high thermal stability and relatively high hardness, and has become a unique new type of material. [0003] In the field of architectural decoration, compared with marble and granite, glass-ceram...
