Process purpose — germanium tetrachloride making from source raws and reverts. Process is carried on decomposition reactors.

Process purpose — germanium dioxide making. Process is carried on interaction between germanium tetrachloride and water.

Process purpose — polycrystalline metallic germanium making. Process is carried on in hydrogen service in tube-type furnaces with two temperature zones.

Process purpose — metallurgical refining by multiple recrystallization, zone refined polycrystalline germanium making. Process is carried on multiple-tube units with moving inductors.

Process purpose — making of monocrystalline germanium with defined electrophysical and optical specification. Crystal growing made by Czochralski method.

Process purpose — making of different shapes germanium blanks. Machining is made by using of different types of equipment: calibration, shearing, grinding equipment for flat and spherical surfaces, chamfering and irregular shapes machining equipment.
