ISO - 21079-1

Chemical analysis of refractories containing alumina, zirconia and silica — Refractories containing 5 % to 45 % of ZrO2 (alternative to the X-ray fluorescence method) — Part 1: Apparatus, reagents and dissolution

active, Most Current
Organization: ISO
Publication Date: 15 April 2008
Status: active
Page Count: 18
ICS Code (Chemical analysis): 71.040.40
ICS Code (Refractories): 81.080
scope:

This part of ISO 21079 specifies methods for the chemical analysis of AZS (alumina, zirconia, and silica) refractory products (containing 5 % to 45 % of ZrO2) and raw materials, using traditional ("wet") methods, inductively coupled plasma atomic emission (ICP-AE) spectrometry and flame atomic absorption (FAA) spectrometry. It covers apparatus, reagents and dissolution methods[1].

This part of ISO 21079 is not applicable to MgO-based refractories.

[1]This part of ISO 21079 gives alternatives to the X-ray fluorescence (XRF) method given in ISO 12677.
