Van-Arkel's process

Vedclass · Answer

(C) The $Van-Arkel$ process is a method used for the refining of metals like $Zr$ and $Ti$. In this process,the crude metal is heated in an evacuated vessel with iodine to form a volatile metal iodide,such as $ZrI_4$. The metal iodide is then decomposed on a tungsten filament at a higher temperature $(1800 \ K)$ to obtain pure metal. Therefore,the $Van-Arkel$ process employs the thermal decomposition of volatile iodide compounds.

Metal	Refining Process
$I$. $Hg$ (Mercury)	Distillation
$II$. $Cu$ (Copper)	Poling
$III$. $B$ (Boron)	Zone refining
$IV$. $Ti$ (Titanium)	Liquation
