Kyanite is a typically blue silicate mineral, commonly found in aluminium rich metamorphic or sedimentary Rocks.Kyanite is a member of the alumino-silicate series, which includes the polymorphs, alusite and sillimanite, which have the same chemical composition (Al2O3.SiO2) as alusite and sillimanite but it is distinguished from those two minerals by its physical properties.
KYANITE, SILLIMANITE AND ANDALUSITE 30-2 30 Kyanite, Sillimanite and Andalusite Kyanite, sillimanite and andalusite are three aluminium silicate minerals having the same chemical composition (Al 2 O 3.SiO 2) but differing in physical properties. These minerals are also known as 'super-refractories' in view of their special refractory properties.

Sillimanite consists of chains of aluminum octahedra linked by alternating aluminum and silica tetrahedra. Goodness knows, before 21st century computer modelings, some of us 20th century geology students struggled with self-made cardboard and glue cut-outs of these polyhedra--assembling them to visualize Sillimanite's structure.
IMAR 7 th Edition. Kyanite, andalusite, and sillimanite are naturally occurring anhydrous aluminum silicate minerals. Each has the same chemical formula, Al 2 SiO 5, but differing crystal structures, making them mineral polymorphs.These variances in crystal structure give somewhat unique physical properties to each of the three minerals, and each is used in slightly different ways by modern ...
Sillimanite consists of chains of aluminum octahedra (green) joined by chains of alternating silica and aluminum tetrahedra (yellow and blue).The first image shows a cross section of the structure.You can see how the tetrahedra bridge the gaps between neighboring octahedra.The second images is slightly inclined to the cross section which showing four layers of the structure.
Kyanite, whose name was derived from the Greek word Kyanos which means Blue. It is typically blue silicate mineral, commonly found in Aluminum - Rich Metamorphic Pegmatite or Sedimentary Rocks. Kyanite is a member of the Aluminosilicate series, which includes the Polymorph Andalusite and the Polymorph Sillimanite.
Kyanite is a polymorph with two other minerals: andalusite and sillimanite. A polymorph is a mineral that shares the same chemistry but a different crystal structure with another, or other, minerals. Since the three minerals form under different conditions of temperature and pressure, they are diagnostic for …

Sillimanite refractories contain 50–60% Al 2 O 3 and 45–35% SiO 2 and are made from naturally occurring Sillimanite, Kyanite or Andalusite fired at 1500–1800 °C. Refractories made from these materials have similar properties as alumina refractories, but slightly poorer mechanical strength and thermal conductivity.
