Abstract：A new process of preparation of skin - colored ultrafine powder ZnO is reported inthis paper by adding suitable amount of ammonium bicarbonate to basic zinc carbonate during itsthermal decomposition. The ZnO product is characterized by the methods of chemical analysis,XRD,TEM,etc.The results indicate that the Zn0 powder obtained by this process is skin - colored with spherical shape and ultrafine diameters. The powder can be used in the fields of cosmet-ics, medicines, pigments, etc.

Key words：ultrafine powder;zine oxide; thermal decomposition
