摘要：

A novel way for electrification of mineral particles by electron beam irradiation was proposed. The effect of irradiation dose on charge/mass ratio was investigated experimentally. The charge/mass ratio of electrified mineral powders after irradiation was measured by an instrument based on the principle of electrostatic induction. The experimental results showed that the charge/mass ratio is largely dependent on radiation dose and electric physical properties of minerals. The mechanism of electrification by electron beam irradiation is discussed. It is suggested that the essential of electrification by electron beam irradiation is a process of retardation and charge deposition of incident electrons in materials.
