Heat for vaporization is supplied by gas-or oil-fired burners by conduction and radiation through a silicon carbide arch that separates the zinc vapors and the products of com- bustion. Molten zinc from either a melting pot or sweat furnace is charged through a feed well that also acts as an air lock.


semiconductor material: the metalloids germanium (first used in 1947) and silicon (first used in 1954)—in amorphous, polycrystalline and monocrystalline form—, the compounds gallium arsenide (1966) and silicon carbide (1997), the alloy silicon-germanium ).
