Micron ceramic ball material as well as preparation method and application thereof
The invention provides a micron ceramic ball material as well as a preparation method and application thereof, a water-in-oil emulsion is formed by emulsifying a ground water-phase suspension, then water-phase ceramic powder is obtained by layering and washing, and the micron ceramic ball material is obtained by calcining. The micron ceramic ball material is formed by stacking nanocrystals of a network structure and has rich micropores, the adsorption capacity of the micropores is combined with the adsorption capacity of the nanocrystals, so that the micron ceramic ball material shows excellent adsorption performance, and it can be guaranteed that heavy metal ions adsorbed on the micron ceramic ball material have good binding capacity; in addition, by regulating and controlling the calcination temperature, the micron ceramic ball material still has good mechanical strength and adsorption capacity under high external acting force, is stable in structure and has the advantages of being high in recovery rate and capable of being repeatedly used, the preparation process is simple, large-scale production is easy, and the method is suitable for industrial production. Belongs to the field of nano-structure preparation of micron-sized ceramic materials.
本发明提供了一种微米陶瓷球材料及其制备方法和应用，通过对研磨后的水相悬浮液进行乳化处理形成油包水型乳浊液，然后经分层、洗涤得到水相陶瓷粉，再通过煅烧处理得到微米陶瓷球材料，该微米陶瓷球材料由网络状结构的纳米晶堆叠而成，具有较为丰富的微孔，微孔的吸附能力结合纳米晶的吸附能力，使其表现出优异的吸附性能，并且能够保证吸附在其上的重金属离子具有良好的结合能力，实现对重金属离子的吸附与回收再利用，此外通过对煅烧温度进行调控，使得微米陶瓷球材料在高外加作用力下仍具有良好的机械强度和吸附能力，其结构稳定，具有高回收、可重复利用的特点，制备工艺简单，易放大生产，属于纳米结构制备微米级陶瓷材料领域。
