Preparation method of ultra-large zirconite ceramic material
The invention belongs to the technical field of refractory materials, and particularly relates to a preparation method of an ultra-large zirconite ceramic material. A zirconite green body of which thesintering temperature is 10-110 DEG C lower than that of an ultra-large zirconite ceramic material is used as a supporting material, and the zirconite ceramic material is sintered under a reducing atmosphere condition, so that the sintering temperature of the zirconite material is increased, the sintering range is expanded, the problem of sintering cracking of an ultra-large zirconite ceramic material is solved, the bending creep rate and the foaming rate of the obtained product are remarkably improved, the service life of an overflow brick is prolonged, and the quality of liquid crystal glass is improved. The method is simple, feasible, scientific, reasonable and convenient for large-scale industrial production.
本发明属于耐火材料技术领域，具体的涉及一种超大型锆英石质陶瓷材料的制备方法。以烧结温度比超大型锆英石陶瓷材料低10‑110℃的锆英石质坯体作为支撑材料，采用还原气氛条件下烧成，提高了锆英石材料的烧结温度并且扩大了烧结范围，解决了超大型锆英石陶瓷材料烧成开裂的问题，并且所得制品的弯曲蠕变速率、发泡率有显著改善，有利于延长溢流砖的使用寿命，并提高液晶玻璃的质量。该方法简单易行、科学合理，便于大规模工业生产。
