Fine ceramics (advanced ceramics, advanced technical ceramics) — Methods for chemical analysis of metal impurities in silicon dioxide powders — Part 2: Inductively coupled plasma-mass spectrometry

Scope

This document specifies methods for the chemical analysis of metal impurities present in silicon dioxide powders as fine ceramics using inductively coupled plasma-mass spectrometery (ICP-MS).
It stipulates the methods for the determination of metal impurities in silicon dioxides powders. Silicon dioxide powders are decomposed by acid decomposition. The aluminium, calcium, cadmium, chromium, copper, iron, lead, lithium, magnesium, manganese, nickel, potassium, sodium, titanium, zinc, and zirconium contents in the test solution are determined by ICP-MS.
