2016-3-27  zirconium and hafnium solution is passed through a series of liquid-liquid extractions, stripping, and scrubbing steps to separate zirconium from hafnium. Liquid-liquid extraction, using methyl isobutyl ketone (containing thi ocyanate) as a solvent, separates zirconium from hafnium by preferentially extracting hafnium into the solvent phase.

Zirconium (Zr) Chemical properties, Health and

Zirconium. Zirconium is a very strong, malleable, ductile, lustrous silver-gray metal. Its chemical and physical properties are similar to those of titanium. Zirconium is extremely resistant to heat and corrosion. Zirconium is lighter than steel and its hardness is similar to copper. When it is finely divided, the metal can spontaneously ignite
