401Graphite By Harold A. Taylor, Jr.1 Natural crystalline flake graphite was in short supply in 1978-79. Prices of imported flake graphite increased significantly in both years. Supplies of Mexican amorphous graphite remained sufficient, and substitution of it for scarcer crystalline flake appears to have been moderately successful. Domestic production of natural graphite increased in 1978 in both quantity and value from the 1977 level, and then decreased in 1979 from that of 1978, but quantitative data are not released for publication. Production will be impacted by the closing in late 1979 of the only domestic mine. Production of manufactured graphite in 1978 increased 13% in quantity over that of 1977, and production in 1979 increased 9% over that of 1978. Imports of natural crystalline and amorphous graphite in 1978 were up 15% in quantity over the 1977 level, but decreased 8% in 1979 from the 1978 level.

Legislation and Government Pro. grams.—National stockpile goals for strategic graphite, proposed in 1976 and reaffirmed in 1977 by the Federal Preparedness Agency of the General Services Administration, remained unchanged in 1978-79. Stockpile goals and inventories for each type of graphite are shown in table 2. There were no acquisitions or disposals of strategic graphite in 1978 or 1979. The 3-year trial suspension on the import duty for natural crystalline graphite was e~tended until the end of June 1981.
