Characteristics of dust particulates (charging, movement and temperature) in magnetic fusion devices with different plasma parameters are discussed. It is shown that the charge quantity of dust particulates is obviously influenced by the ratio between electron and ion temperatures; secondary electron emission reduces the charge quantity; the charging relaxation time of dust particulates in fusion plasma is much shorter than in laboratory plasma; dust particulates speed reach hundreds of meters per second under the action of ion drag force; the lifetime of carbon dust in fusion plasma is on the millisecond scale. The results are consistent with experimental observations.
