Sillimanite, kyanite and andalusite - energymining.sa.gov.au

The minerals sillimanite, kyanite and andalusite are all aluminium silicates having the same chemical formula (Al 2 SiO 5) but different crystal structures and physical properties. They form during metamorphism of alumina-rich sediments. Production worldwide in 2013 was 440,000 tonne, mostly andalusite from South Africa, the bulk of which is used for manufacture of mullite (Al 6 Si 2 O 13 ...

30 Kyanite, Sillimanite and Andalusite K yanite, 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. These minerals have special property of undergoing conversion into mullite (3Al 2 O 3 ...

The triple point andalusite — Sillimanite — Kyanite ...

The triple point in the Al2SiO5 polymorphic system has been determined experimentally; it lies at 6.5±0.5 kb and 595±10° C. This result differs strongly from the data of other experimental investigations on this system; the reasons for this are discussed. The new data given here for the phase boundaries kyanite/sillimanite and andalusite/sillimanite as well as the resulting position of the ...

Utilisation of sillimanite minerals, their geology, and ...

The aluminium-silicate polymorphs sillimanite, andalusite and kyanite decompose to a mixture of mullite and silica glass during calcination. Mullite is an essential component of high-alumina refractories forming the inner lining of furnaces and high-temperature vessels widely used in the production of metals, ceramics, glass and cement. Sillimanite, andalusite and kyanite constituted 2%, 74% ...

The significance of the aluminium silicates in ...

The aluminium silicate system with its common polymorphs kyanite, andalusite and sillimanite, is treated as an example of the interplay between experimental and field experience in advancing understanding of the conditions and controls of metamorphism. If pressure and temperature are the lone controls, the equilibrium coexistence of the three polymorphs in nature should be confined to a point ...

The phase equilibrium between sillimanite and …

Abstract. The thermodynamic equilibrium between sillimanite and andalusite has been determined from the measured phonon spectra. The corresponding aluminium silicate triple point is found to be in the range T=420° C-440° C and P=3.0–3.2 kbars.From the comparison of calorimetrically determined specific heat functions with those calculated from lattice vibrations additional effects of ...

Aluminium silicate, Al2SiOs, has three different crystalline forms: kyanite, andalusite and sillimanite. Because each is stable under a different set of temperature-pressure conditions, and all are commonly found in metamorphic rocks, these minerals are important indicators of geological hisorty of rock bodies. a) Referring to the attached thermodynamic data, argue that at 298K the stable ...
