Abstract

Atomic force microscope (AFM) is widely used for determining of surface performance of materials with smoother surface. In this research, atomic force microscope was used in morphology determination of powder material. Samples were dispersed in aqueous system by ultrasound wave and prepared on mica sheet. Multiple mappings of different powder samples, such as sintered products of ferrous oxalate, ferrous oxalate with lamella structure, lithium carbonate, boron powder, ferric oxide and zinc oxide, were investigated and analyzed in detail. Results showed as follow: ferrous oxalate sintered in different processes and conditions presented different morphology characteristics both in shape and size. Ferrous oxalate obtained from special process presented two-dimension lamella structure and self-assembly phenomenon. The shape and size of lithium carbonate particles were uniform. Defects of mappings on boron powder, ferric oxide and zinc oxide reflected problems of the preparation process before scanning. Determination experiences of powder material in AFM technology could be obtained.
