摘要
研究了制备纳米BaSO4粒子的多种制备方法 ,用透射电子显微镜和激光粒度分析仪对合成纳米粒子的形貌、大小及粒度分布进行了表征分析 ,实验发现不同制备方法对纳米粒子大小及形貌均有影响 ,同时各种制备方法所得的纳米BaSO4粒子平均粒径小、分布窄 。
In this paper, the nano BaSO 4 particles with diffe rent size and shape were prepared using three methods.The size and shape of syn thetic nano-particles were observed by TEM,and their particle-size distributi ons were measured by Coulter Nuplus.The results showed that different synthetic methods affected the size and shape of nano BaSO 4 particles and every synthet ic nano-particle methods showed small size and narrow size distribution.Also t heir synthetic mechanisms were discussed.
