微波干燥法制备纳米硅酸铝

The Synthesis of Nano-aluminum Silicate by Microwave Technique

介绍了微波干燥法制备球形纳米硅酸铝粒子的方法,并用透射电镜(TEM)、红外光谱(IR)对粒子进行了表征。讨论了pH值和表面活性剂对粒子大小的影响,结果表明:微波加热使粒子更均匀,粒径大小与pH值成反比,表面活性剂的加入可以防止纳米粒子团聚。

The approach of preparation of nano - sized aluminum silicate by microwave technique was presented and its characteristics were shown by virtue of SEM and FTIR spectrum. The ingredients of particle size, including pH and surfactant were also discussed.
