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
