Kyanite being formed as a high pressure polymorph, andalusite a low pressure polymorph and sillimanite that forms at high temperatur The Uses of Kyanite: Refractory products such as bricks, mortar and general kiln furniture that can withstand high temperatures in furnaces Moulds used in the casting of high temperature metals
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 energi All of the polymorphs share a common crystal structure, ie, chains of AlO 6 edge-shared octahedra parallel to the c-crystallographic axis
and temperature conditions, sillimanite is often the predominant polymorphic mineral Kyanite, characterized by the densest crystal structure of the polymorphs, is most often associated with metamorphic rocks formed under high pressure and mid to lower temperatur Economic deposits are found in a variety
