Fine ceramics (advanced ceramics, advanced technical ceramics). Methods for chemical analysis of impurities in aluminium oxide powders using inductively coupled plasma-optical emission spectrometry
1 Scope
This document specifies methods for the chemical analysis of impurities present in
aluminium oxide powders used as a raw material for fine ceramics.
Aluminium oxide powders are decomposed by acid pressure decomposition, acid decomposition
or alkali fusion. The calcium, chromium, copper, iron, magnesium, manganese, potassium,
silicon, sodium, titanium, zinc and zirconium contents in the test solution are determined
by an inductively coupled plasma-optical emission spectrometer (ICP-OES).
