AbolishedMetallic and its compound powder--Determination of specific surface and particle size by air permeating method
金属及其化合物粉末 比表面积和粒度测定 空气透过法
Application Summary AI generated
This standard specifies the air permeating method for determining the specific surface area and average particle size of metallic and metallic compound powders. It is applied in the metallurgical industry for quality control and characterization of raw materials such as metal powders, oxides, and carbides used in powder metallurgy, ceramics, and catalyst manufacturing. The method is particularly relevant for testing contexts where rapid, non-destructive measurement of fine powder fineness is required.
