Fine ceramics (advanced ceramics, advanced technical ceramics) — Determination of trace magnetic impurities in oxide ceramic powder

Scope

This document provides a method for separation, collection, and determination of trace magnetic impurities in oxide ceramic powders.
This document applies to the determination of the total content of magnetic impurities (iron, cobalt, chromium, nickel, and zinc) between 0,005 and 20 mg/kg which can be attracted by magnet.
This document is applicable to oxide ceramic powders such as zirconia (ZrO2) and alumina (Al2O3). It can also serve as a reference for the separation and determination of trace magnetic impurities in other non-oxide ceramic powders.
