High-strength porous ceramic filter and preparation method thereof
The invention belongs to the technical field of ceramic materials, and particularly relates to a high-strength porous ceramic filter and a preparation method thereof. According to the high-strength porous ceramic filter, ceramic material components comprise 50-90 wt% of zirconium oxide and 10-50 wt% of a product D; the preparation method of the product D comprises the following steps: (1) carryingout low-temperature calcination by taking active aluminum hydroxide as a raw material to obtain a product A; (2) mixing the product A with nano alpha-aluminum oxide, silica sol and metal salt, addingwater, and performing ball milling and mixing to obtain a product B; (3) drying and calcining the mixed product B to obtain a product C, cleaning the product C with distilled water, and drying the washed product to obtain a powder mixed product D; according to the high-strength porous ceramic filter, the strength at normal temperature and high temperature is obviously improved, the metal impact resistance is improved, meanwhile, the cost is obviously reduced, and the high-strength porous ceramic filter is suitable for industrial production; the invention also provides a preparation method thereof.
本发明属于陶瓷材料技术领域，具体涉及一种高强度多孔陶瓷过滤器及其制备方法。所述的高强度多孔陶瓷过滤器，陶瓷材料组分包括50‑90wt％的氧化锆和10‑50wt％的产物D；所述产物D的制备方法为：(1)以活性氢氧化铝为原料进行低温煅烧后得到产物A；(2)产物A与纳米α‑氧化铝、硅溶胶、金属盐混合，加水球磨混合得产物B；(3)混合产物B经过烘干、煅烧得到产物C，产物C经过蒸馏水清洗后，烘干得到粉体混合产物D。本发明的高强度多孔陶瓷过滤器，在常温、高温强度都有明显提升，抗金属冲击能力提高，同时成本明显降低，适合工业化生产；本发明还提供其制备方法。
