Title:
METHOD FOR PREPARING LEAD SLAG GLASS-CERAMIC BY OXIDIZING AND CONDITIONING SILICON-RICH SILICON SLAG
Document Type and Number:
WIPO Patent Application WO/2023/273199
Kind Code:
A1
Abstract:
Disclosed in the present invention is a method for preparing lead slag glass-ceramic by oxidizing and conditioning silicon-rich silicon slag, belonging to the technical field of resource utilization of smelting slag rich in elemental silicon. In the present invention, silicon slag rich in elemental silicon is mixed with an oxidizing agent, a fluxing agent and a clarifying agent according to a formula ratio, and a conditioned raw material having uniform dimensions is obtained after ball milling and screening; the conditioned raw material is oxidized and melted at a high temperature to form an oxidized molten conditioned material. The molten conditioned material is further mixed with hot lead slag and then quenched with water to obtain a base glass, and the obtained base glass is subjected to heat treatment to form a glass-ceramic. In the present invention, smelting slag rich in elemental silicon is oxidized and conditioned, and mixed with the hot lead slag to prepare a base glass, and a glass-ceramic is obtained by adjusting a heat treatment process for the base glass. The present invention has the advantages of simple technological processes, high production efficiency and low costs, achieves the goal of high-value conversion of silicon-rich silicon slag and lead slag, and is easy to popularize and apply in industrialization.
