Abstract

The invention relates to the technology for producing bismuth germanate crystals. A method includes loading of raw material and heating thereof in a furnace, solid phase synthesis under heating with a rate of 10-20 deg/min, holding and cooling in a crucible. Raw material is loaded in the bunker, the later is installed above the crucible and is placed in the furnace previously heated to 1100+50 oC, then it is heated with a rate of 50-100 deg/min to 915 ± 15 °C and then rate is lowered to the value known for solid phase synthesis and heating is continued to 1100 ± 50 °C and overflowing of melt in the crucible, holding is carried out during 2-6 h, after that the crucible is cooled starting from the lower part thereof with a rate of 50-200 deg/h to 970 ± 70 °C and further with a rate of 200-600 deg/h.
