TAP DENSITY MEASUREMENT VESSEL, TAP DENSITY MEASUREMENT TOOL AND TAP DENSITY MEASUREMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a tap density measurement vessel, a tap density measurement tool and a tap density measurement method for repeatably and accurately measuring a tap density.;SOLUTION: The measurement vessel is provided with a first vessel 2 and a second vessel 3 disposed on the first vessel 2 and communicating with the first vessel 2. The second vessel 3 can be detached from the first vessel 2. The measurement vessel includes a sample. After the sample is attached to a tapping apparatus and tapped, the second vessel 3 slides on an upper end face of the first vessel 2, a level of the sample is limited by a lower end face of the second vessel 3, mass of the sample remaining in the first vessel 2 is measured and divided by sample storing volume of the first vessel 2 and the tap density of the sample is measured.;COPYRIGHT: (C)2004,JPO
