Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

INTERNATIONAL STANDARD ISO 3169:2023(E)
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).
