APPARATUS FOR MELTING AND/OR PURIFYING INORGANIC COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for melting and/or purifying an inorganic compound by which the danger in continuous operation is minimized or largely removed. ;SOLUTION: This apparatus has a crucible for storing a material to be heated, and a high-frequency system for heating the material by supplying a high-frequency energy to the material of the crucible. The high-frequency system has a high-frequency oscillation circuit having an induction coil coiled around the periphery of the crucible, and an oscillator, and at least a second oscillator capable of being connected to the induction coil.;COPYRIGHT: (C)2001,JPO
