| description | Experimental and theoretical studies have been conducted on the measurement of the contact potential difference between a powder bed and a metal. A new model was proposed for the analysis of the experimental data. The model analysis indicated that accurate contact potential differences are obtained only when the electric charge of the powder bed is assumed to be zero. It was found that the absolute value of the contact potential difference decreased with an increase in relative humidity. The contact potential changed with the particle surface-modification by methanol vapor. However the original contact potential difference was obtained again when the methanol evaporated completely from the particle surface. † This report was originally printed in J. Soc.
