摘要
为了给玻璃窑熔池提供一种综合性能优良的材料,按m(ZrO_(2))∶m(Al_(2)O_(3))=4∶1将ZrO_(2)粉和Al_(2)O_(3)粉充分混合后在电弧炉内熔融,再将得到的电熔氧化锆-刚玉共晶料加工成不同粒度,随后按一定的颗粒级配配料并混合均匀,压制成型后在1750℃下烧结,制备了新型氧化锆基复合材料,分析了物相组成和显微结构等性能,并与33^(#)锆刚玉砖和41^(#)锆刚玉砖进行了抗玻璃液侵蚀性对比。结果表明:新型氧化锆基复合材料结构致密,且化学纯度高、组分无低熔点物,具有良好的抗热震性。与33^(#)锆刚玉砖和41^(#)锆刚玉砖相比,新型氧化锆基复合材料被高温玻璃液侵蚀后未见孔洞,无针状气孔及缺陷,无液相渗入,与玻璃液没有发生反应,具有良好的抗玻璃液侵蚀性能。
To provide a material with excellent comprehensive properties for the glass kiln melting pool,zirconia powder and alumina powder were fully mixed according to the ratio of m(ZrO2)∶m(Al_(2)O_(3))=4∶1 and fused in an arc furnace.The obtained fused zirconia-corundum eutectic material was processed into different particle sizes,batched according to a certain particle size distribution and mixed evenly.After pressure molding and sintering at 1750℃,new zirconia-based composites were prepared.The phase composition and microstructure of the composites were analyzed.The molten glass corrosion resistance of the composites was compared with that of zirconia corundum bricks 33^(#) and 41^(#).The results show that the new zirconia-based composites have a dense structure,high chemical purity without low melting point components,and good thermal shock resistance.Compared with zirconia corundum bricks 33^(#) and 41^(#),after corroded by high temperature molten glass,the new composites have no corrosion cavities,no needle-like pores or defects or liquid phase infiltration and no reaction with molten glass,showing good corrosion resistance to molten glass.
