Czochralski Method
Lab Grown Sapphire (By Czochralski Process); Most Recommended To Produce Top Quality
The right chemical ingredient selected is super heated above its degree of the melting point. This is done in a crucible surrounded by the electrical heating gadget. A minute piece of ruby crystalline solid is hooked to a metal rod. The craved crystal will slowly grow on this seed crystal. To enhance the process, the seed crystal is systematically lowered into the processing crucible till it’s completely immersed in the molten emulsion.
The seed crystal immersed, is uniformly rotated using the metallic rod to which it was attached. This is to regulate the contact temperatures making sure; they remain constant for the better quality. As the rod is continued to be rotated, the nutrient chemical material adheres itself to the seed crystal, crystallises, and pulls out of the molten solution raising the rod. The nutrient chemical is held within the solution to ensure it’s fully used. The cropping up tip is kept wholly in contact with the molten solution until all nutrient material is used up.
The cropping rate of the tip may be simultaneous to a level such that large crystals are pulled out from the mixture with diameter measurements surpassing two within 50 millimetres (mm). Crystal lengths may exceed 40 by one meter (mm). Standard rates, in this case, may be measured as 4 within a hundred millimetres per hour.
