Inventories shown in table 2 omit all committed surplus stocks. Comparison with the December 31, 1971 inventory indicates a disposal of 10,363 tons during 1972; however, actual shipments totaled only about 3,000 tons, 45% greater than the 2,100 tons entering the market in 1971. An administration proposal to reduce the objectives of many stockpiled materials, including graphite, and dispose of the resulting surpluses was under consideration in early 1973. DOMESTIC PRODUCTION Production of natural graphite in the United States declined further in 1972, although at a slower rate than the year before. The only operating mine continued to be that of Southwestern Graphite Co. near Burnet, Tex., which produced a small flake crystalline graphite. Interest in domestic graphite mining was stimulated by the growing shortage and higher prices of imported natural graphite. Several former graphite mines and other properties were being considered for investigation during the year. A deposit in Alaska, estimated to be quite large, was investigated by the Geological Survey. Minor production has occurred there in the past, but its remote location and lack of access as yet render it uneconomic at current prices. Production of manufactured graphite regained an upward trend in 1972 after slipping slightly the year before. Ouput of 275,311 tons was up 7% from the 256,137 tons produced in 1971. Total value of production increased 17% to $183.6 million from $157.3 million the previous year. All metallurgical uses of manufactured graphite showed marked improvement as the metals industries recovered from their slump of 1970—71. Most other uses, such as mechanical products made of graphite, also fared well. The outlook for graphite fibers brightened somewhat as the result of its initial commercial acceptance in specialty sporting goods, which represents its first nondefense application. Manufactured graphite was produced in 26 plants owned by 18 companies during 1972. Some production may have taken place at other locations as well, particularly by users for in-house consumption. The considerably augmented list, as compared to that published last year, includes a number of plants making specialty products such as high-modulus fiber which had not been included in the manufactured graphite survey in previous years.
