Abstract
Disclosed is a method of adding silicon to aluminum. The method is characterized in that silicon particles having a diameter ranging between 2 mm and 50 mm are added to a molten aluminum together with a flux represented by the general formula XaMFb, where 'X' represents an element included in the third or fourth period of the Periodic Table, 'M' is a III or IV group element of the Periodic Table, and 'F' is fluorine. A part of the flux may be added in the form of coating on the surface of the silicon particle.
