摘要/Abstract

摘要： 铝-锆-硅(AZS)材料是玻璃工业窑炉中关键的砌筑材料,其显微结构和ZrO₂晶相的稳定性对材料的抗钠钙玻璃液侵蚀性能具有显著影响。本文采用化学分析、高温X射线衍射分析、抗玻璃液侵蚀试验及电子显微镜等测试分析方法,研究了配加少量Y₂O₃的熔铸41^#AZS材料的理化性能。结果表明:配加少量Y₂O₃,可以起到稳定剂的作用,可改善该材料的显微结构,Y₂O₃主要赋存于首先结晶的ZrO₂晶体及枝晶中,致使这些结晶相的颗粒变细,而且ZrO₂相变温度范围变小,相变程度降低,改善了ZrO₂晶体及共晶体的稳定性,从而显著提高该材料的抗玻璃液侵蚀性能。

Abstract: AZS material is a key building material in the furnace of glass industry, the microstructure of material and the stability of zirconia phase have significant effects on the corrosion resistance to the molten soda-lime glass. The physical and chemical properties of fused-cast 41^#AZS materials with a small addition of yttrium oxide were studied by means of chemical analysis, high temperature X-ray diffraction, glass corrosion resistance test and electron microscope. The results show that the microstructure of material is improved by adding a small amount of Y₂O₃ stabilizer, Y₂O₃ is mainly deposited in the ZrO₂ crystals and dendrites, which firstly crystallize, resulting in the refinement of the particles of these crystalline phases. The temperature range of ZrO₂ phase transition becomes smaller, the degree of transformation reduces, and the stability of ZrO₂ crystal and eutectic improves, thus the corrosion resistance of material to glass melt is significantly improved.

Key words: refractory, fused-cast AZS material, yttrium oxide, stabilizer, corrosion resistance, glass furnace
