Abstract
An improved apparatus characterized by an R-F coil, a crucible for confining a silicon melt, and a susceptor for supporting the crucible facilitating an electrical coupling of the coil with the melt. The susceptor comprises a pair of susceptor halves of a thickness less than two skin depths, each being the mirror image of the other, disposed in mutually opposed, electrically insulated relation, while the crucible comprises a quartz body supported by the graphite susceptor, whereby the R-F coil is electrically coupled with the melt.
