Production of a high value ceramic material: Silicon …

2019-4-20 · Silicon carbide is often referred to as “carborundum”: this vernacular term commemorates a word coined by Edward G. Acheson in 1892 to describe crystals that he made in an experiment which had the real goal of making a diamond-like crystal from carbon and alundum. Using a primitive furnace of his own design, he in fact made SiC.
