As a member of the alumino-silicate family, it has the same chemistry as sillimanite and kyanite but differs in crystalline structure. Andalusite is volume-stable at elevated temperatures and achieves a slight permanent expansion of about 1.5% at around 2730F. The andalusite deposit in Hillsboro, NC is very clean with low iron and alkali impurities.
The Pyrofrac series of andalusite phyrophyllite materials are beneficeated to maximize the available andalusite.
