Abstract

The specific surface of nickel, iron, copper and silver powders in different sizes has been measured by using self-made Blaine's air permeability apparatus. The specific apparatus surface and average particle size obtained by above are in the ranges of 690-26400cm²/g and of 0.26-ll.lμm respectively, which are consistent with the upper and lower limits in the literature published.
