molten zone मीनिंग इन हिंदी

Then a small amount of antimony is placed in the molten zone, which is passed through the pure germanium.
The molten zone carries the impurities away with it and hence reduces impurity concentration ( most impurities are more soluble in the melt than the crystal ).
A polycrystalline rod of ultra-pure electronic grade silicon is passed through an RF heating coil, which creates a localized molten zone from which the crystal ingot grows.
A variety of heaters can be used for zone melting, with their most important characteristic being the ability to form short molten zones that move slowly and uniformly through the ingot.
