  • Kyanite, andalusite and sillimanite are minerals with the same chemical formula, but with different crystal structures and chemical properties.
  • The theoretical composition is about 63 percent alumina and 37 percent silica.
  •  The three minerals are sometimes referred to as the “sillimanite group.”
  • The mineral can occur in metamorphic rocks but is not often in a form that can be easily extracted.
  • Kyanite, andalusite and sillimanite ,these minerals convert to mullite  and silica upon “calcining,” or heating from about 1,250 degrees Celsius to 1,500 degrees Celsius.
  • Kyanite is available in varying grain sizes down to 325 mesh and in calcined-to-mullite form.
  •  The decomposed mullite form is volume-stable with temperature increase, while the raw form of kyanite displays definite expansion during heat up.
  •  The United States is the largest producer, with all of the kyanite coming from central Virginia.
  • Kyanite Mining Corp-oration’s ore deposits are kyanite quartzites containing 15 to 40 percent kyanite and usually about 5 percent of other minerals such as mica, pyrite and rutile.
  • South Africa is the leading producing country of andalusite, with an estimated 235,000 metric tons of marketable output of the mineral.
  • France produces an estimated 65,000 tons per year of andalusite.
  •  China reportedly has some production of andalusite, but official data have not been received by the U.S. Geological Survey.
  • The interlocking grain structure of andalusite, kyanite and mullite gives added mechanical strength to refractories and other nonrefractory ceramic materials.
  • It is used primarily as an additive in the production of high-temperature ceramic products such as furnace bricks, but is also used in abrasives, brake shoes, cookware, and a wide variety of other industrial and consumer products.
  • Kyanite has proven invaluable in cements, ramming mixes, and mortars for this purpose.
