Overview

Kyanite is a naturally occurring Alâ‚‚SiOâ‚… polymorph that converts to mullite on high-temperature calcination, undergoing controlled expansion. It is highly valued in refractory formulations, precision investment casting shells, and specialty ceramic systems requiring low shrinkage and high refractoriness.
