TANTALUM AND NIOBIUM: A REVIEW OF WORLDWIDE INDUSTRY STATISTICS

摘要

The Tantalum-Niobium International Study Center collects data from its membership that are consolidated to track industry mining, processing, and shipments of tantalum and niobium products in numerous forms. Data are collected semi-annually and reported on that same basis to the membership. Growth trends in the tantalum industry remain strong, with the demands for capacitor grade powder and wire leading the requirements for continued expansion of the raw material base. Niobium growth trends continue on the same path as shown in previous years with the production of HSLA grade ferroniobium being the leading product in terms of production requirements, as this single product represents almost 90% of the niobium product sold in the world marketplace. The data will be reviewed covering the period from the early 1990s up through June 2000.
