Crystal growth machine by the Czochralski method(CZ)

This machine for growing crystals by Czochralski method. CZ wide range crystal growing machine “Oxide”. Applied for lab and industry crystal making. Automatical diameter control system. High precision weight meter system with exclusive direct weight control design. Czochralski furnace “Oxide” crystal growth of different type materials: BGO, LSO, LiNbO3, YAG, PbWO4 and many other. Oxide crystals by using the Czochralski method, such as lithium niobate, lithium tantalate, yttrium-aluminum-garnet (YAG), gallium-gadolinium garnet, etc (GGG).


  • Automatic growing ingot predetermined form (automatic diameter control)
  • The system of direct weighing growing ingot (exclusive)
  • Bottom rod with working and accelerate adjustable movement speed (supply for Customer request)
  • Frequency heating (up to 20 kHz) with automatic frequency oscillatory circuit
  • Furnace is equipped with preinstalled software on a perpetual commercial license
  • Closed water cooling system with proximity sensors control the flow and temperature of cooling water lines
  • Power stability of the heating system is not less than ± 0.01%
  • Software enables programs to form heating cooling, each of which comprises a sequence of independent segments, defined by three parameters: the increment of the voltage on the segment length of a segment of time and limit the voltage on the segment. It is possible to maintain these programs in the electronic memory of industrial computer. The software implemented the ability to "hot" switch from one program to another.
  • Many other features will added by Customer demand
