Carborundum powder is just the one to meet all function needs. In the past 20 years, Haixu Abrasives has provided customers solutions to anti-corrosion and wear resistance industries. Black carborundum powder and green carborundum powder are the most commonly used materials. It turned to be an ideal choice that works well.
Silicon carbide (SiC), also known as carborundum (/ ˌ k ɑːr b ə ˈ r ʌ n d əm /), is a semiconductor containing silicon and carbon. It occurs in nature as the extremely rare mineral moissanite. Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive.
Carborundum also was the source for graphite lubricants. Acheson discovered that when "Carborundum" (silicon Carbide) was superheated to 7,500 degrees Fahrenheit, the silica vaporizes and leaves behind artificial graphite. The Carborundum specimens that are collected are manufactured in blast furnaces at abrasive factories.

Carborundum is the trade name for silicon carbide, an artificial crystal invented in 1890. Although the result of a failed experiment that sought to create diamond by putting carbon under pressure, it was quickly discovered that carborundum was a useful abrasive.
The Norton Company is quite possibly the world's leading producer of grinding wheels and coated and bonded abrasives. It is the leading producer of silicon carbide. From its inception as an offshoot of a small pottery works in Worcester, Massachusetts, in 1885, Norton pioneered the development of new abrasives.
Let us discuss the carborundum meaning, Silicon carbide (SiC), also referred to as carborundum, is a silicon-carbon semiconductor. Moissanite, an exceptionally rare mineral, is found in nature. Since 1893, synthetic SiC powder has been mass-produced as an abrasive.
