Monocrystalline whisker

High aspect ratio, microscopic, single crystal particles

A monocrystalline whisker is a filament of material that is structured as a single, defect-free crystal. Some typical whisker materials are graphite, alumina, iron, silicon carbide and silicon. Single-crystal whiskers of these materials are known for having very high tensile strength. Whiskers are used in some composites, but large-scale fabrication of defect-free whiskers is very difficult.
