FIELD: chemistry. ^ SUBSTANCE: invention relates to chemical technology for extracting inorganic materials. The method of activating aluminium involves immersing an aluminium sample into gallam in the melting temperature range of the gallam and/or aluminium in the presence of ultrasonic vibrations. The apparatus for activating aluminium has an ultrasonic radiator, an ultrasonic generator, an output current sensor for the generator, a comparator and a command device. The working face of the ultrasonic radiator is acoustically connected to the end surface of the aluminium sample. The excitation input of the radiator is connected through the current sensor to the output of the ultrasonic generator, and the output of the current sensor is connected through the comparator to the stop input of the command device, whose output is connected to the control input of the ultrasonic generator. ^ EFFECT: high output and quality of end products and high environmental safety of production. ^ 6 cl, 3 dwg, 1 tbl, 3 ex |
