布莱恩空气透过法的测量范围

MEASURING RANGES OF BLAINE'S AIR PERMEABILITY METHOD

摘要: 用自制布莱恩（Blaine）空气透过法装置测量了九种粗细不同的镍粉、铁粉、铜粉及银粉的比表面,其值在690～26400cm²/g之间,平均粒径为0.26～11.1μm。

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.
