摘　　要：Nanosized zinc carbonate was prepared in the droplet of nano reactor based on microemusion. The influences of the concentration of the surfactant and reactant on the diameter of nanoparticles were studied and the kinetic parameters of thermal decomposition reaction were determined. It can be shown from experimental results, the diameter of the droplet in the microemulsion which have dissolved reactant zinc nitrate and sal volatile is between 4.9nm and 7.7nm, 6.2nm and 12.4nm, respectively. Nanosized zinc carbonate prepared by the method of microemusion has shown good dispersion, narrow distribution and light agglomeration. The particle size of nanosized zinc carbonate is between 5nm and 40nm, and its kinetic parameters of thermal decomposition reaction activation energy E and reaction order n are 110kJ· mol- 1 and 0.9, respectively.
