Production of oxides single crystals (Al2O3, Y3Al5O12) of 25 mm diameter and 75 mm length.

  In Czochralski technique crystals are grown by slow pulling of a seed/wire/ capillary from the free surface of a melt of the material contained in a crucible. A growth station, to contain crucible and minimizes heat losses (by conduction and radiation), is made using appropriate ceramic tubes, felts, and wools. The shape of the crystal can be determined by controlling the diameter of the growing crystal through the manipulation of the melt temperature and pull rate depending on properties of the material under consideration. 

This technology is to grow single crystal of Al2O3 and Y3Al12O5 of 25 mm dia and 75 mm length.

                                                       SALIENT FEATURES 

 Growth of single crystal of oxide material.

 Oriented crystals.

 Controlled Diameter.

APPLICATIONS

 Growth of Scintillator single crystals like YAP, YAG, GGAG etc.

 Growth of oxide crystal used as Gems like sapphire and Ruby.

 Substrate/window material single crystal.
