Scope
This part of GB/T 17414 specifies the method for determining the amount of beryllium in beryllium ores by catalytic polarography.
This part is applicable to beryllium ores, and also to the determination of low concentrations of beryllium in lithium, rubidium, cesium, and tantalum, niobium ores.
Measurement range: 0.0001% to 0.40% (mass fraction) beryllium content (calculated as beryllium oxide).
