Preparation of Zinc Sulfide Nano-particles by High-Gravity Method
超重力法制备纳米硫化锌

By using zinc nitrate and hydrogen sulfide as source materials, nanometer zinc sulfide was synthesized by a high gravity method in a rotating packed bed. The effect of aging time on product sizes was investigated and 48h was chosen. Well-dispersed nanometer zinc sulfide particles with a sphalerite crystal phase were prepared. The crystal structure, optical properties, size and morphology of the product were also characterized by XRD, UV-Vis spectrophotometer and TEM. The results show that the average particle size of ZnS obtained is about 30nm and the conversion rate is 97.5 percent.
