ISO/CD 21068-2

Chemical analysis of raw materials and refractory products containing silicon carbide, silicon nitride, silicon oxynitride and sialon — Part 2: Determination of loss on ignition, total carbon, free carbon and silicon carbide, total and free silica and total and free silicon

Scope

This part of ISO 21068 specifies analytical techniques for the determination of volatile components by thermal treatment at specified temperatures, and methods for the determination of the total carbon content, free carbon, silicon carbide, total and free silicon and free and surface silica content of silicon carbide, silicon nitride, silicon oxynitride and sialon containing raw materials and refractory products.
