THE DETERMINATION OF THE SURFACE AREA AND PORE DISTRIBUTION OF FINE IRON OXIDE PARTICLES

The surface quatities of fine iron oxide particles are studied. The pore distribution and surface a area are determined and calculated. The results show that the surface area is 290m/g, 830m/g and the middle-pore(20~50A )is the main part of the fine iron oxide particles prepared by the colloid chemical method.
