XB/T 610.1-2015Chemical analysis methods for samarium-cobalt permanent magnet alloy. Part 1: Determination of samarium, cobalt, copper, iron, zirconium, gadolinium, praseodymium content (English PDF)

Foreword

XB/T 610-2015 "samarium cobalt permanent magnet alloy chemical analysis method" is divided into three parts.

--- Part 1. Determination of samarium, cobalt, copper, iron, zirconium, gadolinium, praseodymium;

--- Part 2. Determination of calcium and iron content atomic absorption spectrometry;

--- Part 3. Determination of oxygen content pulse - infrared absorption method.

This section XB/T 610.1 for the first part.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This section replaces XB/T 610.1-2007.

This section compared with the XB/T 610.1-2007, the main technical changes are as follows.

--- Expand the scope of application, covering the samarium cobalt 1. 5 and samarium cobalt 2.17 permanent magnetic alloy powder;

--- Added Method 2 plasma emission spectrometry;

--- Instead of the original standard method of melting the filter paper method;

--- Added to the elemental copper, iron, zirconium, gadolinium, praseodymium amount determination;

--- Modify the quality of the sample, changed from 0.1g to 0.8g;

--- No longer using the vanadium internal standard correction.

This section contains X-ray fluorescence spectrometry (method 1) and inductively coupled plasma-atomic emission spectrometry (method 2). When two analytical methods when there is an overlap in the measurement range, use method 2 as the arbitration method.
