Minerals yearbook, 1992: Columbium (niobium) and tantalum. Annual report

Technical Report ·
OSTI ID:5265934
Columbium is used principally as an additive in steelmaking, which annually accounts for about 80% of the U.S. reported consumption. The outlook for steel is discussed in the annual report for iron and steel. The outlook for columbium will also be dependent to a lesser degree on the performance of the aerospace industry. Continued reduction in military spending is expected to lead to reduced aerospace shipments throughout the decade. For the past decade, more than 60% of the tantalum consumed in the United States was used to produce electronic components, mainly tantalum capacitors, with major markets in recent years being computer and communication systems. Annual U.S. apparent consumption of tantalum is anticipated to be less than 400 tons through most of the 1990s. The major components of U.S. supply-demand relationships for tantalum in 1982-92 are given.
