Sillimanite is composed of aluminum silicate, which is a polymorph; sillimanite, kyanite and andalusite all share the same chemical composition (Al2SiO5), but each exhibit differing unique crystal structures. Sillimanite forms as orthorhombic, hexagonal crystals, whereas kyanite and andalusite crystals are both formed as triclinic crystals.
