KYANITE, ANDALUSITE AND SILLIMANITE - Virginia

2020-9-9  KYANITE, ANDALUSITE AND SILLIMANITE Kyanite, andalusite and sillimanite are naturally occurring polymorphic minerals that have the same chemical composition, Al 2 SiO 5, yet differ in their crystal structures and thermodynamic properties. These minerals, collectively referred to as the sillimanite minerals group, are valued for their high

Kyanite - an overview ScienceDirect Topics

Depending on the P, T conditions, aluminosilicates Al 2 SiO 5 exhibit three polymorphs: andalusite, sillimanite, or kyanite (Fig. 7). The polymorphic transformations are sluggish because of the very low differences between their Gibbs free energies.

Kyanite - an overview ScienceDirect Topics

Al 2 SiO 5 exists as three polymorphs: sillimanite, andalusite, and kyanite. In the first of these, sillimanite (the low-pressure form), all the aluminum ions are in a four-coordination system with oxygen; andalusite, stable at higher pressures, has half the aluminum ions surrounded by five nearest neighbors; and in kyanite, the highest pressure form, the aluminum ions all have the highest coordination number of 6

Sillimanite (also called Bucholzite) is a polymorph with two other minerals: kyanite and andalusite.A polymorph is a mineral that shares the same chemistry but a different crystal structure with another, or other, minerals. Sillimanite is the rarest of the three trimorphs.. A variety of sillimanite is called "fibrolite".
