Preparation method of monodisperse micron-sized hollow ceramic microspheres
This invention belongs to the technical field of ceramic microspheres preparation, and specifically relates to a preparation method of monodisperse micron-sized hollow ceramic microspheres. The preparation method comprise that following steps: taking a siloxane monomer as a reaction monomer and deionize water as a reaction dispersion medium, carrying out polymerization reaction on the monomer by utilizing an alkaline catalyst to obtain polysiloxane microsphere powder, sintering the polysiloxane microsphere powder at a high temperature for ceramicisation of the polysiloxane microsphere powder to prepare the monodisperse micron-sized hollow ceramic microspheres with the particle size of 1-6 mu m. The method has simple steps, easily controlled reaction conditions and high production efficiency, and can realize large-scale batch production
本发明属于陶瓷微球制备技术领域，具体涉及一种单分散微米级中空陶瓷微球的制备方法，以硅氧烷单体为反应单体，去离子水为反应分散介质，利用碱性催化剂催化反应使得单体进行聚合反应，反应得到聚硅氧烷微球粉末，然后将聚硅氧烷微球粉末在高温下烧结，使得聚硅氧烷微球粉末陶瓷化，制得粒径为1‑6μm单分散微米级中空陶瓷微球；本发明方法，步骤简单、反应条件易控制、生产效率高，可实现规模化批量生产。
