Preparation of high pure zinc for electronic applications using selective evaporation under vacuum

► 6 N Zn was produced by vacuum distillations of 3 N Zn at 2 kg batch with 67.5% yield. ► Impurities in Zn were determined by ICP-OES, GD-OES and O-N analyzer. ► Impurities removed - Al, Cu, Fe, Sn, Pb, Si, Ca, As, Ag, Sb, Ni, Bi, Mg, Mn, O, N and C. ► Purification efficiency is discussed w.r.t. impurity vapor pressure and mean free path of Zn. ► Crystalline structure of distilled Zn was studied by XRD.
