Abstract:

 Cupric oxalate uniform colloidal particles with different shapes and sizes, such as ultrafine, square. pipe-like and network-like, were prepared in the Triton X-100 n-C6H13OH/c C6H12/Water solution (oxalic acid or cupric nitrate W/O microemulsion system by adjusting the concentration, pH value and temperature of oxalic acid and cupric nitrate solutions. What should be particularly mentioned is the preparation of two types of uniform colloidal particles whose shapes are square and pipe-like respectively. The factors which influence the shapes and sizes of particles are under vigorous control.
