Porous sialon ceramic filter and preparation method thereof
The invention provides a porous sialon ceramic filter and a preparation method thereof, and belongs to the technical field of ceramic products. The porous sialon ceramic material comprises a base material which is prepared from the following raw materials in parts by weight: 20-35 parts of aluminum oxide, 5-18 parts of aluminum nitride, 35-50 parts of metal silicon and 0.01-15 parts of rare earth oxide. According to the sialon ceramic material disclosed by the invention, aluminum oxide, aluminum nitride, metal silicon and rare earth oxide in a specific ratio are used as basic materials, and proper types of sintering aids are added, so that a high-temperature glass phase is formed in the sintering process of sialon ceramic, and an obvious promoting effect is achieved on the sintering process, so that the oxidation resistance and porosity of the material are greatly improved.
本发明提供了一种多孔赛隆陶瓷过滤器及其制备方法，属于陶瓷制品技术领域。一种多孔赛隆陶瓷材料，包括基础料，所述基础料由如下重量份的原料制成：氧化铝20～35份，氮化铝5～18份，金属硅35～50份，稀土氧化物0.01～15份。本发明赛隆陶瓷材料以特定配比的氧化铝、氮化铝、金属硅和稀土氧化物作为基础料，加入合适种类的烧结助剂，使赛隆陶瓷在烧结过程中形成高温玻璃相，对烧结过程起到明显的促进作用，从而大大提高材料的抗氧化性能和气孔率。
