KEMET Corporation, as we know it today, was officially formed on December 21, 1990. However, the history of KEMET actually began a long time ago. Kemet Laboratories was established by Union Carbide Corporation in 1919 to purchase the Cooper Research Company of Cleveland, Ohio, which had invented a promising high-temperature alloy. The name "KEMET" is a blend of the words "chemical" and "metallurgy." KEMET''s first product used this high-temperature alloy for grid wires in vacuum tubes. In 1930, the product line was expanded to include barium-aluminum alloy getters, an essential element in every vacuum tube. KEMET''s development of automatic machinery allowed production of high-quality getters in the huge quantities needed to match the rapid expansion of vacuum tube usage. In fact, it is estimated that over 80[%] of the vacuum tubes used by the Allies during World War II contained KEMET getters.
