Etymology:
The word "carborundum" is a portmanteau of the Latin words "carbo" ("coal") and "corundum" (a type of mineral).
Meaning:
Carborundum is a synthetic compound consisting of silicon carbide (SiC). It is an extremely hard and refractory material, used as an abrasive and in various industrial applications.
Origin:
Carborundum was first synthesized in 1891 by the American inventor and chemist Edward G. Acheson. Acheson was experimenting with the production of graphite using an electric arc furnace. However, he accidentally produced a new material that was much harder than graphite. He named this new material "carborundum" due to its composition and similarity to corundum in hardness.
Historical Significance:
The invention of carborundum marked a significant advancement in the field of abrasives. It was the first commercially viable synthetic abrasive material, and its superior hardness and durability made it ideal for a wide range of industrial applications, including cutting, grinding, and polishing. Carborundum is still widely used today as an abrasive, as well as in high-temperature applications, electronics, and other industries.
