Contact electrification of solid particles
Proceedings of the Physical Society, 1941Solid particles carry with them electrostatic charges from contact with the storage vessel. The sign of the charge acquired in the air of the laboratory was determined for metal particles which were poured either from a silica bowl or from a glass beaker, and for particles of insulators and semiconductors which parted contact with containers of silica,

Contact electrification of coal and minerals
Journal of Electrostatics, 1994Abstract The contact electrification of coals from France, the Great Britain and the United States has been studied. Additionally, the behavior of the most abundant minerals in coal (quartz, calcite and pyrite) has been investigated. The charge transfer upon repeated contacts with a copper plate has been measured.

Electrification following the contact of solids
Contemporary Physics, 1961Abstract The charge found on solids after they have been rubbed together can only be a direct consequence of friction when the rubbing is vigorous; more usually, the charging is the result of contact, rubbing complicating the phenomenon. Opinions differ regarding the origin of contact charging, but certain experiments suggest a working hypothesis ...

Surface Contamination and Contact Electrification
1987When two materials are touched together and then separated, we find, in general, that charge has transferred between them. This phenomenon is known as contact electrification or contact charging. It is most apparent when one or both of the contacting materials is an insulator, because of the ability of an insulator to retain charge. Contact charging is
