FIELD: chemistry.
SUBSTANCE: profiled monocrystals of germanium are grown on seed crystal from liquor with application of shape-former, placed in crucible and having holes in the place where its lower part adjoins crucible bottom for removal of excessive liquor; first initial charge of germanium is placed into shape-former and space between crucible wall and shape-former and melted, with height of liquor in said space being at the level 0.85÷0.95 of height of liquor in shape-former, after that, seed crystal rotating with angular speed in the range 5÷20 rev/min is placed into liquor of shape-former, and crystal is grown in radial direction until its diameter approaches diameter of shape-former, then rotation of crystal is stopped, regulated reduction of temperature to complete crystallisation of entire liquor volume in shape-former with formation of its excess and flowing of liquor through holes of shape-former into space between crucible and shape-former is carried out, after which entire volume of liquor in space between crucible and shape-former is crystallised by further reduction of temperature.
EFFECT: increased yield of suitable production due to obtaining monocrystals of germanium of universal shape without structural defects, free of mechanical stress, and simplification of technological process.
