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.
