The story
The company was founded in 1886 as the National Carbon Company, which in 1917 was acquired by Union Carbide and became its Carbon Products Division.
In 1914, the company introduced the first 12-inch-diameter graphite electrodes.
In 1956, the company received an Academy Award for the development and production of a high-efficiency yellow flame carbon for motion picture color photography.
Between 1956 and 1978, the company developed high-performance carbon fibers; this would be recognized in 2003 with a National Historic Chemical Landmark from the American Chemical Society.
In 1985, the company developed advanced technology for carbon/carbon composite material used in spacecraft.
Union Carbide was reorganized in 1989, renaming the Carbon Products Division as the UCAR Carbon Company.
In 1990, the company introduced first 30-inch-diameter graphite electrodes for UHP DC arc furnaces.
In 1995, the company developed new graphite for the US Advanced Battery Consortium for a lithium-ion battery in electric vehicles.
