Abstract
Embodiments of the present invention relate to a furnace system for growing crystals. The furnace system comprises a crucible for growing a crystal and a furnace comprising a housing having an inner volume. The housing comprises a through hole connecting the inner volume with an environment of the housing. An insulation plug is movably insertable into the through hole for controlling a heat extraction out of the crucible by radiation, wherein the insulation plug is free of a force transmitting contact with the crucible.
Claims17
A furnace system for growing crystals, the furnace system comprising:
- a crucible for growing a crystal;
- a furnace comprising a housing having an inner volume forming a heating zone;
- wherein the crucible is arranged within the inner volume, wherein the housing comprises a through hole connecting the inner volume with an environment outside of the housing;
- and an insulation plug which is movably insertable into the through hole for controlling a heat extraction out of the crucible by radiation, wherein the insulation plug is free of a force transmitting contact with the crucible, wherein the insulation plug comprises a heat radiation section which forms a free end of the insulation plug facing a bottom surface of the crucible;
- and wherein the insulation plug comprises an insulation section which forms a free end of the insulation plug facing the environment outside of the housing.
