摘要
以锆英石荒坯为骨料,锆英石粉为细粉,磷酸二氢铝为结合剂,研究了锆英石微粉的加入量对玻璃窑用锆英石捣打料的性能影响。利用扫描电子显微镜对锆英石微粉的显微形貌进行分析,通过研究发现:随着锆英石微粉的加入量增加,材料的高温性能明显增强。当锆英石微粉的加入量在5%时其烧结性能最好;微米级的锆英石微粉可以在玻璃熔融温度下形成片状的陶瓷结合相,在很大程度上提高了材料的力学性能。
Using zircon billet as aggregate, zircon powder as powder and aluminum dihydrogen phosphate liquid as binding component, this paper studied how different amount of micro zircon powder as admixture affects the performance of zircon ramming mass. With the help of scanning electron microscope, this paper also found the performance of the material under high temperature was improved as zircon powder amount was increased. The best case scenario occured with addition of 5% zircon powder to the mass. Micro level zircon powder will form a kind of heterogeneous plate-shape ceramic bond,improving mechanics performance of the material to a great extent.
