Scope
This section specifies the method for determining the amount of zirconium oxide (hafnium) by the gravimetric method of phenylhydroxyacetic acid. The arbitral analysis uses this method.
This section is applicable to the determination of the amount of zirconium oxide (hafnium) in zirconium oxide refractory materials. The measurement range (mass fraction) is 50.00% to 98.00%.
