GB/T 18114.4-2010 《Chemical analysis methods of rare earth concentrates - Part 4：Determination of niobium oxide, zirconium oxide and titanium oxide contents - Inductively coupled plasma atomic emission spectrometry》 Related products

The GB/T 18114.4-2010 standard specifies in detail the determination method of oxidation niobium (Nb2O), zirconium oxide (ZrO _ 2) and titanium oxide (TiO _ 2) in rare earth concentrates. The method adopts Inductance Coupled Plasma Light Emission Spectrometry (ICP-OES), melts samples by sodiumhydrate and sodium peroxide, and uses Standard addition method and Standard Linear dispersion method in different media (hydrofluoric acid and muriatic acid). The measurement range is Nb2O _ 0.070%~ 0.20%, ZrO _ 1.00%~ 5.00%, TiO _ 0.10%~ 4.00%. This standard provides technical support for the accurate analysis of these oxides in rare earth concentrates.
