BS EN ISO 3169:2025

This standard BS EN ISO 3169:2025 Fine ceramics (advanced ceramics, advanced technical ceramics). Methods for chemical analysis of impurities in aluminium oxidepowders using inductively coupled plasma-optical emissionspectrometry is classified in these ICS categories:

• 81.060.30 Advanced ceramics

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).
