摘要
研究了微粒子氧化铁的表面性质,测定并计算了其孔径分布和比表面积。结果表明,用胶体化学法制制备的微粒子氧化铁,以中孔(20～50A)为主,在所测的两种试样中其比表面积分别为290m^2/g和830m^2/g。
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.
