摘要
以芒硝-硫化钡法生产的沉淀硫酸钡为对象,对普钡、超细钡和精细钡粉体的粒度、形貌与结构及表面ζ电位和随pH的变化规律进行了分析表征,对改善沉淀硫酸钡流动性和吸油量,以及对沉淀硫酸钡表面物理化学性质的调控和进行表面处理等应用研究有参考价值。
Taking the precipitated barium sulfate produced by sodium sulfate-barium sulfide method as a sample,there are three kinds of the product,i.e.common,fine and ultrafine powder.The particle size,shape,structure and ζ-potential and their variation with pH value are characterized.It is a valuble reference for the improvement of fluidity and oil absorption of precipitated barium sulfate,the controlling of the physical and chemical properties of the product and the surface treatment of the product.
