 Foundries used about 44% of domestic zircon consumption in 1978-1979. The
remainder was consumed by refractory, shrasive, ceramic, metal, and other
industries. Domestic zircon was marketed in proprietary mixtures for use
as foundry sand, zircon-refractory heavy mineral sand blends (with kyanite,
sillimanite, and staurolite), weighting agents, zircon-TiO2 blends for welding
rod coatings, and sandblasting applications. The zircon-bearing foundry sand
was reportedly designed to provide consistent high-quality performance at
low cost for critical casting applications. 
 In 1978 and 1979 baddeleyite concentrate from the Republic of South Africa
was used mainly in the manufacture of aluminazirconia abrasives and also
for ceramic colors, refractories, and other uses. 
 An estimated 80% of U.S. zirconium metal consumption was used in commercial
water-cooled nuclear reactors for fuel cladding and pressure tubes, 15% in
naval nuclear reactors, and 5% for corrosionresistant applications in the
chemical industry and for photographic flashbulbs. 
 U.S. shipments of zirconium mill products declined about 10% in 1978 and
15% in
