  • Method of growing single crystals
    Patent number: 3960647
    Abstract: In a method of growing of single crystals which are practically free from misorientation, namely single crystals of metals which exhibit an allotropic change of state at a temperature below their melting points, single crystals of the raw metal which has undergone unidirectional solidification are heated to a temperature between the allotropic transformation point and the melting point of the metal, the single crystals are maintained during a predetermined period in the vicinity of this temperature and cooled to a temperature below the allotropic transformation point. The single crystals are then annealed in order to obtain complete recrystallization of the metal and finally cooled to room temperature.
