Organic composite porous ceramic material and preparation method thereof
The invention discloses an organic composite porous ceramic material and a preparation method thereof, and relates to the technical field of porous ceramic processing. The organic composite porous ceramic material disclosed by the invention is composed of silicon dioxide, diatomite, aluminum powder and modified cellulose. The preparation method comprises the following steps: uniformly mixing the components, grinding the mixture into mixed powder, adding a water-soluble adhesive and water into the mixed powder, uniformly mixing, carrying out freeze drying to obtain a porous ceramic precursor, and carrying out high-temperature sintering on the porous ceramic precursor. The organic composite porous ceramic material provided by the invention has very high porosity and uniform pore distribution, and the pore size and shape can be controlled. The organic composite porous ceramic material can also be used for storing hydrogen, has the characteristics of high hydrogen storage capacity, simplehydrogen absorption and desorption operation, high-temperature and high-pressure resistance and the like, is good in cycling stability and can be repeatedly used for multiple times, and the prepared product is high in strength and not easy to deform.
本发明公开一种有机复合多孔陶瓷材料及其制备方法，涉及多孔陶瓷加工技术领域。本发明公开的有机复合多孔陶瓷材料是由二氧化硅、硅藻土、铝粉和改性纤维素组成，通过将组分物均匀混合并研磨成混合粉末，然后将水溶型粘合剂和水加入到混合粉末中混合均匀，冷冻干燥制得多孔陶瓷前驱体，再将多孔陶瓷前驱体高温烧结而制得。本发明提供的有机复合多孔陶瓷材料具有很高的孔隙率，且孔隙分布均匀，并可控制孔隙大小和形状。本发明还可用于贮存氢气，具有贮氢容量高、吸放氢操作简单、耐高温高压等特性，循环稳定性好，可重复多次使用，且制备的制品强度高、不易变形。
