Refinement of zirconia
Did you know?
Zirconium is a chemical element with the symbol Zr and atomic number 40. The name zirconium is derived from the name of the mineral zircon, the most important source of zirconium. The word is related to Persian zargun (zircon; zar-gun, "gold-like" or "as gold"). It is a lustrous, grey-white, strong transition metal that closely resembles hafnium and, to a lesser extent, titanium. Zirconium is mainly used as a refractory and opacifier, although small amounts are used as an alloying agent f… WebIntroduction Van Arkel's process to Refine Titanium/ Zirconium Seema Makhijani 104K subscribers Subscribe 3.2K views 2 years ago General principles of extraction class 12 by …
