Biortho-germanate single crystals

MDA Crystals has developed the industrial technology of growing Biortho-germanate large single crystals with Czochralski method using growers “Krystall-3M”.

Technological process is to foresee bull growing as cylinder and “opposite cone” having diameter up to 100 mm and length up to 360 mm.

 

Perspective application of crystals:

  • detection of ionizing radiation;
  • environment control;
  • radiation control of the nuclear plants;
  • high energy physics;
  • computer tomography.
