连续流动氩吸附测定小表面积
SMALL SURFACE AREA MEASURED BY ABSORPTION OF CONTINUOUS FLOW ARGON
-
摘要: 本文作者为粉末和多孔烧结体小表面积测定设计了一种新型简单的样品管,并提出使用氩气作吸附质,以彻底消除热扩散的影响,从而能够用连续流动法准确地测定小至0.01m2的表面积。Abstract: In order to completely eliminate the influence of thermal diffusion a new type of simple sample cell for determining the small surface area of powder and sintered compacts was designed and argon was used as absorbate, therefore the surface area as less as 0.01m2 can be determined by continuous flow method.
