Abstract
This invention aims at providing a silicon electromagnetic casting apparatus for accurate and easy manufacturing of high quality silicon ingots. This apparatus uses a furnace vessel, a conductive crucibleinstalled in the internal part of the furnace vesseland an induction coilinstalled on the outer circumference of the crucible. Constant pressure is maintained in the internal part of the furnace vesselusing a prescribed gas and the silicon inside the above mentioned crucibleis solidified after melting it by induction heating by applying voltage on the induction coil. The induction coilis made by placing 2 induction coilsandhaving different induction frequencies one above the other.
