Supercharging of dust particles in a plasma with a two-temperature energy distribution of electrons is studied. Influence of the thermal-field emission and the secondary electron emission on the charge of dust particles is investigated. The maximum possible charge in view of the limited tensile strength of dust particles, which can be disintegrated under the action of the ponderomotive force, is determined. It is experimentally and theoretically demonstrated that the charge of micron-sized particles can be as high as 10{sup 6} electron charges.
