GB/T 17416.2-1998 Method for chemical analysis of Zirconium ores.Determination of Zirconium and Hafnium contents.X-ray fluorescence spectrometric method (English Version)
This standard specifies the determination method of zirconium content and chromium content in zirconium ore. This standard is applicable to zirconium ores, and also to the determination of zirconium and hafnium contents in other rare metal ores. Measuring range: 16×10-6~8.7×10-2zirconium dioxide; 34×10-6~3.0×10-2hafnium dioxide.
