摘要/Abstract

摘要： 为了更好地综合利用白云鄂博矿选冶固废,本文以白云鄂博萤石尾矿和包钢高炉渣为主要原料,采用一步烧结法研究了不同原料配比对制备微晶玻璃的影响。采用DSC、XRD、SEM、万能试验机、多道γ能谱仪进行表征分析,研究了不同原料配比对制备微晶玻璃的影响。结果表明:不同原料配比时,微晶玻璃主晶相为斜辉石、透辉石、鳞石英;随着萤石尾矿和高炉渣质量配比的增加,微晶玻璃颜色逐渐加深,且抗折强度先升高后降低,再升高再降低;当萤石尾矿和高炉渣质量配比为5 ∶5时,微晶玻璃抗折强度最高,达到76.85 MPa,主晶相为斜辉石和透辉石,晶粒大小均匀,排列规则;当萤石尾矿与高炉渣质量配比为2 ∶8时,微晶玻璃产品符合B类装饰装修材料标准,当萤石尾矿与高炉渣质量配比为3 ∶7、5 ∶5、6 ∶4时,微晶玻璃产品符合C类装饰装修材料标准。

Abstract: In order to make comprehensive use of solid waste from Bayan Obo Mine, the effects of different raw material ratios on the preparation of glass-ceramics were studied by one-step sintering method with fluorite tailings of Bayan Obo and blast-furnace slag of Baotou Steel as main raw materials. DSC, XRD, SEM, universal testing machine and multi-channel γ spectrometer were used to characterize and analyze the effects of different raw material ratios on the preparation of glass-ceramics. The results show that the main crystalline phases of glass-ceramics are clinopyroxene, diopside and tridymite when the ratio of raw materials is different. With the increase of the mass ratio of fluorite tailings to blast-furnace slag, the color of glass-ceramics gradually darkens, and the flexural strength increases first and then decreases, then increases and decreases. When the mass ratio of fluorite tailings to blast-furnace slag is 5 ∶5, the flexural strength of glass-ceramics is the highest, reaching 76.85 MPa, and the main crystalline phase is clinopyroxene and diopside, with uniform grain size and regular arrangement. When the mass ratio of fluorite tailings to blast furnace slag is 2 ∶8, the glass-ceramics product meet the class B decoration material standard, and when the mass ratio is 3 ∶7, 5 ∶5, 6 ∶4, it meets the class C decoration material standard.
