<p><P>PROBLEM TO BE SOLVED: To provide a powder composition whose charge is suppressed in various surrounding environment. <P>SOLUTION: The powder composition contains mainly powder particles having a particle size of 5μm or less, and contains a carbon nanometer material having electric conductivity. The powder composition relaxes a charged state by quickly moving charges through the carbon nanometer material when charges are given to the powder particles by friction or the like. Since electrification of the powder composition is suppressed, aggregation or attachment to a pipe wall is suppressed. Since the carbon nanometer material has no hygroscopicity and has stable properties under various temperatures, various humidities, and various pressures, electrification under various surrounding environments is suppressed and drop in fluidity is also suppressed. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
