Worked out is the procedure of the decrease of partial pressure for the reduction component H2 down to a critical value (< 30 Pa) in the process of crystallization. This allows to diminish the melt stoichiometry and to grow the crystals with higher economical and functional characteristics meant for the use in standard optical and optoelectronical devices without any limitations.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
