CONTROLLING TEMPERATURE OF CRUCIBLE INSIDE FURNACE Russian patent published in 2018 - IPC C30B11/00 C30B35/00 C30B29/20 F27B14/08 

FIELD: chemistry.

SUBSTANCE: invention relates to a furnace system for growing crystals, which comprises furnace (120) comprising housing (121) having inner volume (V_i) forming a heating zone, wherein furnace housing (121) comprises through hole (124) connecting inner volume (V_i) with an environment of housing (121), crucible (110) for growing a crystal, mounted in inner volume (V_i), heat insulation plug (101) which is movably inserted into through hole (124) for controlling heat extraction out of crucible (110) by radiation, wherein heat insulation plug (101) is free of a force transmitting contact with crucible (110), and support plate (106) made of a high thermal conductivity material having a heat transfer coefficient greater than 90 W/(m⋅K) and installed between lower surface (112) of the crucible (110) and support area (123).

EFFECT: invention provides good thermal insulation of the furnace housing with effective heat transfer from the crucible to the environment, which improves the controlled curing of the liquid material when growing crystals.
