STRONTIUM
(Data in metric tons of contained strontium,1/ unless noted)
Domestic Production and Use: No strontium minerals have been produced in the Un
States since 1959. The most common strontium mineral, celestite, which consists
primarily of strontium sulfate, was imported exclusively from Mexico. A company
Georgia was the only major U.S. producer of strontium compounds. Primary stront
compounds were used in the faceplate glass of color television picture tubes, 69
ferrite ceramic magnets, 11%; pyrotechnics and signals, 9%; and other, 11%.

STRONTIUM
Events, Trends, and Issues: Although there is celestite in the National Defense
Stockpile, none of it is stockpile grade; its total value is listed as zero. Th
stockpile goal was reduced to zero in 1969, and at that time the stockpile conta
both stockpile- and nonstockpile-grade material. Since then, all the stockpile-
celestite has been sold. Although the nonstockpile-grade celestite has been off
for sale, none has been sold since 1979. The fiscal year 1996 Annual Materials
announced at the end of September by the Defense Materials Stockpile Center,
identified 3,300 tons of celestite to be offered for disposal.

World Resources: Resources in the United States are several times the reserve b
World resources, although not thoroughly evaluated, are believed to exceed 1 bil
tons.
Substitutes: Although it is possible to substitute for strontium in some of its
applications, such a change would adversely affect product performance and/or co
For example, barium could replace strontium in color television picture tube gla
only after extensive circuit redesign to reduce operating voltages that produce
harmful secondary X-rays. Barium replacement of strontium in ferrite ceramic ma
would decrease the maximum energy and temperature characteristics of the magnet.
Substituting for strontium in pyrotechnics would be impractical because the desi
brilliance and visibility are imparted only by strontium and its compounds.
