Sapphire Growth Method - Czochralski Method


The Czochralski Method is a method of crystal growth used to obtain single crystals of semiconductors (e.g. silicon, germanium and gallium arsenide), metals (e.g. palladium, platinum, silver, gold), salts and synthetic gemstones. The process is named after Polish scientist Jan Czochralski who invented the method in 1916 while investigating the crystallization rates of metals.
Tungsten crucible is the medium for growing sapphire in this method.
