Forming apparatus having a specific surface area of ​​the sample for measurement of powder

摘要

Cylindrical shape so that the measuring cell used in the specific surface area measuring apparatus of the powder, the porosity is easily formed cylindrical sample layer of constant (powder layer) with high reproducibility, the upper is open specific surface area measurement sample layer forming cells of the powder comprising a filter constituting the powder filling chamber (1), the bottom of the filling chamber and (2) and (A), the powder filling chamber (1) compaction means (12) powder filled within it becomes from (B), and the filter (2) is transmitted through the air, but it is a filter that does not pass through the powder compaction means of the powder (B Piston cylinder) was set up piston (6) tip (5) a plunger having vents for exhausting outside the cell gas in the powder to at least part of the pressure face (3) and (4) It is a specific surface area measuring apparatus of the powder forming apparatus for measurement of the specific surface area of ​​the powder sample, which is characterized in that it is (7), and the method of forming the sample.
