The powder materials are used in various field of industry as raw or intermediate materials. And many kinds of powder unit operation handle these powder materials, but various phenomena of powder have not yet been elucidated sufficiently. Fundamental relationship between powder surface properties and behavior is expected to be discussed as one of important subjects.<BR>In this paper, calcium carbonate is used as test packing powder and powder packing operation is fundamentally discussed. And the effects of powder surface improvement on initial bulk density distribution are experimentally and thermophsically discussed using X-ray radiograph system. As a results of it, the optimum conditions to generate the most homogeneity of powder density distribution is pointed out to exist.
