A replication of H.J. Rounds LED experimentsEarly, non-systematic and often non-recognized syntheses of silicon carbide had been reported by Despretz (1849), Marsden (1880) and Colson (1882).[3] Wide-scale production is credited to Edward Goodrich Acheson around 1893. He patented the method for making silicon carbide powder on February 28, 1893.[4] Acheson also developed the electric batch furnace by which SiC is still made today and formed The Carborundum Company to manufacture bulk SiC, initially for use as an abrasive.[5] In 1900 the company settled with the Electric Smelting and ¡¦

[Thin filament pyrometry]Main article: Thin filament pyrometryImage of the test flame and glowing SiC fibers. The flame is about 7 cm tall.Silicon carbide fibers are used to measure gas temperatures in an optical technique called thin filament pyrometry. It involves the placement of a thin filament in a hot gas stream. Radiative emissions from the filament can be correlated with filament temperature. Filaments are SiC fibers with a diameter of 15 micrometers, that is 5 times thinner than human hair. Because the fibers are so thin, they do little to disturb the flame and their tempera¡¦
