Doping assisted floating zone crystal growth of decompositional compounds

This article describes floating zone (FZ) crystal growth of decompositional compounds, which is assisted by addition of an extra element to constituent elements. Examples are; FZ crystal growths of WC assisted by B addition and YB50 and ScB19 assisted by Si addition. All they decompose without melting as temperature increased. The addition of the extra element enables the compounds to melt by reducing melting temperature and stabilizing the compound phase.
