1U.S. and estimated data are rounded to no more than three significant digits.
2Owing to incomplete reporting, this table has not been totaled. Table includes data available through April 13, 2007.
3In addition to the countries listed, a number of other nations produce kyanite and related materials, but output is not
reported quantitatively, and no reliable basis is available for estimation of output levels.
4In addition, about 7,000 metric tons of sillimanite clay (also called kaolinized sillimanite) that contains 40% to 48% Al2O3
is produced.
5Reported figure.
