GUAN Jian yi 1,AN Zhi min 2,CAO Ke guang 1,WANG Jin mei 1 (1.Department of Chemical Engineering,Chengde Petrolrum College,Chengde 067000,China; 2.Chengde Environmental Protection Bureau,Chengde 067000,China)  
Co 2O 3 ultrafine particles are prepared with the microemulsion method.And the influential factors of the extracion rate and the particle size are also discussed here.During the process of preparation,TEM is applied for the sample shape and size,together with the spectrophotography for the extraction rate.The isobaric molar heat capacities are measured by an adiabatic calorimeter in the temperature range from 78 to 350K.As a result,the thermodynamic function of Co 2O 3 ultrafine particles to the standard temperature of 298.15K was derived based on the measured heat capacity data.
