SiC fibers in Silicon Nitride (5% mullite) Matrix (CMC) Specimen Preparation

Metallographic etchant database

The key to proper specimen preparation of hard / brittle ceramic matrix composite materials is to first section the sample with the appropriate diamond wafer blade, rough grind with as fine a semi-fixed abrasive as possible, followed by the use of CMP (chemical mechanical polishing) techniques.
