(unit of Union Carbide & Carbon Corp.), Cleveland, Ohio, and King Laboratories, Inc., Syracuse, N. Y. The total output of these two companies in 1947 was about 15 percent greater than in 1946. Apparent consumption increased about 36 percent. Prices for the'metal are not quoted in trade journals but may be obtained diredt~ from the producing companies. *The price varies with the quantity and purity desired. The principal use of barium metal is as a "getter." Bari~im metal has a high affinity for oxygen and other gases; and, when~a small quantity is vaporized in an electronic tube, it absorbs most of the gases remaining* in the tube after mechanical means of evacuation have been used. In this application the barium often is alloyed with * other alkaline-earth metals and with light metals. ~Barium ores and chemicals are discussed in the Barite chapter of * this volume. BERYLLIUM United States consumption of beryl concentrates in 1947 increased substantially over 1946. Combined domestic production and foreign imports were inadequate to meet refiners' raw-material requirements, the deficit being balanced by the transfer to industry of stocks of beryl concentrates held by the Office of Metals Reserve. Domestic Mine Production.—South Dakota and New Hampshire were the more important domestic beryl-producing States in 1947. New Hampshire production in 1947 exceeded that of 1946 by over 12 times, whereas South Dakota output declined by 26 percent. The Ashley Mining Corp., operating at West Rumney, N. H., was the 1 Discussion of radium and mesothorium, formerly included in this chapter, is to be found in the Uranium, Radium, and Thorium chapter of this volume. 2 Figures on Imports and exports compiled by M.
