Fine ceramics (advanced ceramics, advanced technical ceramics) — Methods for chemical analysis of metal impurities in silicon dioxide powders using inductively coupled plasma-optical emission spectrometry ISO 5189:2023

Scope

This document specifies methods for the chemical analysis of metal impurities present in silicon dioxide powders used as a raw material for fine ceramics.
It stipulates the methods for the determination of metal impurity elements in silicon dioxide powders that are decomposed by acid decomposition. The aluminium, cadmium, calcium, copper, iron, lead, lithium, magnesium, manganese, nickel, potassium, sodium, titanium, zinc and zirconium contents in the test solution are determined by inductively coupled plasma-optical emission spectrometry (ICP-OES).
