Abstract

The alumothermic reduction of silica from silicate slag was studied for obtaining a silicon-containing alloy (SCA). A synthetic slag (SS) with composition close to that of phosphorous industry waste (PIW) is used. SS consists of more than 90% silicon dioxide, calcium oxide and less than l0% of other element's oxides. SCA was upgraded by acid leaching up to pure silicon of a fine powder structure. Compensated poly- and mono-crystalline silicon, with resistivity from 0.6 (bottom of crystal) to 4 (top of crystal) Ohm · cm, was grown by Czochralski method using this powder.
