Scope

This document specifies test methods for determination of trace elements in ceramic fibers samples used as the raw material for fine ceramics.

This document stipulates the determination methods of the calcium, magnesium, titanium, zirconium, zinc, copper, chromium, tungsten, nickel, aluminium and iron contents in silicon carbide fibers for fine ceramics. Trace element contents such as calcium, magnesium, titanium, zirconium, zinc, copper, chromium, tungsten, nickel, aluminium, and iron are determined by using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) method.

Purpose

Ceramic fibers, such as silicon carbide (SiC), glass, basalt and so on, are one of the core materials in the 4th industrial revolution application field, as aerospace, defense, mechanic and others industry. Because of its mechanical property, high thermal resistance and chemical resistance. For better applications of ceramic fibers, it is very required to analyse and evaluation their chemical compositions, quickly and exactly because their chemical performance can be effect to the thermos-physical properties. Conventional ceramic materials can be analysed precisely by wet (ICP-OES/-MS) trace element methods, but the method of solid-state direct analysis is essential because ceramic fibers are poorly soluble. In addition, there is no international standard for the chemical analysis of ceramic fibers. For these reason, we suggest the test methods for determination of trace elements for ceramic fibers using laser ablation ICP-MS.
