Foreword
GB/T 16477 "rare earth ferrosilicon alloy and silicon magnesium alloy chemical analysis method" is divided into five parts.
--- Part 1. Determination of total rare earth;
--- Part 2. calcium, magnesium, manganese content - Inductively coupled plasma atomic emission spectrometry;
--- Part 3. magnesium oxide content - Inductively coupled plasma atomic emission spectrometry;
--- Part 4. Determination of silicon content;
--- Part 5. Determination of titanium content by inductively coupled plasma emission spectrometry.
This is Part 3.
This part is the "determination of rare earth ferrosilicon alloy and silicon magnesium alloy of magnesium oxide amount" of GB/T 16477.3-1996
Amendments.
This section compared with the GB/T 16477.3-1996, have the following main changes.
--- By inductively coupled plasma spectrometry instead of magnesium oxide content - Flame atomic absorption spectrometry;
--- Increasing the precision of the terms;
--- Increased quality assurance and control provisions.
