标准简介
This document describes a method for the determination of the total content of zirconium oxide and hafnium oxide in rare earth zirconium based compounds. This document is applicable to the determination of the total content of zirconium oxide and hafnium oxide in yttria-stabilized zirconia (or composite yttrium-zirconium ceramic powder), cerium-zirconium composite oxides, gadolinium ytterbium zirconate and scandia-stabilized zirconia. Determination range (mass fraction): 24.00 % to 96.00 %.
