Preparation method of sintered compact high-zirconium brick
The invention discloses a sintered compact high-zirconium brick and a preparation method thereof. The method comprises the steps of pulping, spray granulation, isostatic compaction and high-temperature sintering, according to the preparation method, micron-sized Y2O3 with monoclinic zirconium oxide with the proportion of 40-70% is mainly used for stabilizing an electric melting zirconium oxide raw material, and 1-5% of nano-sized SiO2 is introduced; according to the method, a uniform structure in which zirconium oxide is uniformly dispersed in a small amount of glass phase is obtained, the prepared sintered compact high-zirconium brick has the characteristics of low porosity, high strength, good erosion resistance and low production cost, and large-size products can be prepared.
本发明公开了一种烧结的致密高锆砖及其制备方法，该方法包括制浆、喷雾造粒、等静压成型和高温烧成；所述制备方法主要使用了具有40～70%比例单斜氧化锆的微米级Y2O3部分稳定电熔氧化锆原料，并引入了1～5%的纳米级SiO2；所述方法获得了一种氧化锆均匀分散在少量玻璃相中的均匀结构，所制备的烧结致密高锆砖具有气孔率低、强度高、抗侵蚀性好、生产成本低的特点，并能实现大尺寸产品的制备。
