1 Scope

This standard specifies the Pr-Nd alloy Two Methods to Measure REE compounds and components. This standard applies to the determination of the compounds of fifteen praseodymium neodymium alloy and REE component. Method 1 Measuring range. Pr10.0% ~ 30.0%, Nd70.00% ~ 90.00%, others 0.05% to 0.50% rare earth elements; Method 2 Measurement range. Pr10.0% ~ 30.0%, Nd60.0% ~ 90.0%, other rare earth elements 0.03% to 0.40%. Method 1 X-ray Fluorescence Spectrometry

2 principle of the method

The sample is dissolved by steam until nearly dry, accurately dilute hydrochloric acid solution to dissolve clear, made of thin samples, each measuring dilute the X-ray fluorescence spectrometer Earth element content and calculate its assigned weight.
