摘要/Abstract

摘要： 利用矿渣制备微晶玻璃是提高矿产资源利用率的主要形式之一。本文以白云鄂博尾矿为原料,采用微波一步法制备了CaO-MgO-Al₂O₃-SiO₂(CMAS)系辉石相矿渣微晶玻璃。选择835 ℃作为晶化温度,研究了微波加热对微晶玻璃析晶行为和微观组织的影响。以La₂O₃作为研究变量探讨了La₂O₃添加对矿渣微晶玻璃析晶行为的作用。与传统的热处理制度相比,微波加热可以在较短的时间内达到较高的析晶效果。同时La₂O₃的添加促进了晶粒细化。由拉曼光谱分析,La离子添加会导致玻璃网络中桥氧的增多,促进了辉石相析晶。在La的添加量为4%(质量分数)时硬度最高,达到了829.22 MPa。

Abstract: Using slag to prepare slag glass-ceramics is one of the main ways to improve the utilization rate of mineral resources. CaO-MgO-Al₂O₃-SiO₂(CMAS) series pyroxene phase slag glass-ceramics were prepared using Bayan Obo tailings as raw materials by microwave one-step method. 835 ℃ was choosed as the crystallization temperature and the influence of microwave heating on the crystallization behavior and microstructure of glass-ceramics were studied. Effect of La₂O₃ addition on the crystallization behavior of slag glass-ceramics were discussed using La₂O₃ as the research variable. Compared with traditional heat treatment system, the microwave heating achieves higher crystallization effect in a shorter time. Here, the addition of La₂O₃ promotes grain refinement. According to the analysis of Raman spectroscopy, the addition of La ion will cause the increase of bridging oxygen in the glass network and increase the tightness and integrity of the crystal. The hardness is the highest when the addition of La is 4% (mass fraction), and the Vickers hardness reaches 829.22 MPa.
