Title: Method for measuring contact potential difference of powder
Inventor: ITAKURA TAKAYUKI
IPC: G01N27/26
Filed: 1995-08-24
Abstract: PROBLEM TO BE SOLVED: To measure the true contact potential difference of a powder in a short time by emitting a soft X-ray to the powder having a particle surface formed out of a polymer or the circumference of the powder to eliminate static electricity, and inserting a material to be treated between vibrating electrodes to determine the contact potential difference of the powder. SOLUTION: A powder layer sample 1 is formed on a lower electrode 2, and an upper electrode 3 is provided opposite to the lower electrode 2. In measurement of contact potential difference, the upper electrode 3 is vibrated by a vibrating mechanism to the lower electrode 2 supporting the statically eliminated sample 1 so as to change the distance between the electrodes, a voltage is applied between both the electrodes 2, 3 by a variable voltage power source 5, and the current is measured by a digital ammeter 6. The voltage when the detected current value is zero is determined as the contact potential difference of the sample 1. The sample 1 is filled in such a manner that the powder has a layer thickness of 1-3mm.  A soft X-ray is used as the static eliminating energy source, one having a dose rate of 10-50 roentgen-hour is used as the soft X-ray source, and preferably emitted for 1-100 seconds.
