Abstract

See full text

The manufacturing method for high-purity Zirconium is characterized by self-propagating high temperature synthesis (SHS) of a raw material having zirconium raw ore containing ZrO2, ZrSiO4, KZr2(PO4)3, or a mixture thereof and a reducing agent that is metal powder, to prepare zirconium intermetallic compound or zirconium nitride, followed by the recovery of high-purity Zr by electrolytic refining the reaction product of the SHS.
