An apparatus and process are provided for directional solidification of silicon by electric induction susceptor heating in a controlled environment. A susceptor vessel is positioned between upper and lower susceptor induction heating systems and a surrounding induction coil system in the controlled environment. Alternating current selectively applied to induction coils associated with the upper and lower susceptor heating systems, and the induction coils making up the surrounding induction coil system, result in melting of the silicon charge in the vessel and subsequent directional solidification of the molten silicon. A fluid medium can be directed from below the vessel towards the bottom, and then up the exterior sides of the vessel to enhance the directional solidification process.
