Carborundum, or interstellar dust, first came into being after being discovered in Arizona from a meteorite that fell from space. Edward G. Acheson pioneered its industrial production by starting production there in 1891.
While attempting to produce artificial diamonds by melting corundum in electrical furnaces, he realized that the resultant compound came close to matching diamond’s hardness and abrasiveness.
It is a synthetic mineral
Carborundum is a man-made mineral composed of silicon and carbon. This manmade mineral is commonly used as an abrasive and cutting edge protector on saws, knives, and other tools, but can also be found in printmaking techniques called carborundum printmaking; this form of collograph printmaking involves applying carborundum grit directly onto aluminium plates before inking up for printing purposes. Carborundum’s durability also makes it ideal for high-powered electronics because of its heat and corrosion resistance – making this material suitable even under pressure!
Edward Goodrich Acheson pioneered large-scale production of carborundum in 1891 when he tried to create artificial diamonds using heat from electrical furnaces to combine natural aluminum oxide (corundum) and carbon into a mixture called “carborundum,” later known as synthetic silicon carbide or SiC.
SiC has many uses, from manufacturing abrasive wheels and cutting tools, to use in semiconductor electronics devices due to its high band gap and resistance to heat and corrosion. Ceramic manufacturers often employ SiC as well, with some even using it during the production of iron in blast furnaces. Though naturally occurring moissanite is rare gem material, nearly all silicon carbide sold worldwide is manufactured.
It is an abrasive
Carborundum is a hard, crystalline mineral composed of silicon and carbon that can be used as an abrasive material due to its durability. Additionally, it weighs relatively little while having low thermal expansion for use in multiple applications; in these forms it’s known as silicocarbide or SiC.
Carborundum material is produced by fusing high-grade silica sand with petroleum coke in an electric furnace at high temperatures, producing both particles and fibers of an abrasive material. Once produced, these particles can be ground into powder for use in making industrial grinding wheels, sandpaper, or other products; additionally it may be sold as an abrasive paint for use on litho stones.
Edward Acheson of Pennsylvania invented the first carborundum abrasives in 1890 after conducting extensive experiments using chemical urea to produce diamonds through intensive heating; instead he discovered it instead produced silicon carbide or “carborundum.”
In the 1920s, Carborundum began developing new products based on composite and ceramic technology and relocated to Niagara Falls where hydroelectric power was cheap and abundant. A large plant on Buffalo Avenue included buildings for bonded abrasives (Building 31) and molding. By 1950s Carborundum expanded internationally through acquisitions before eventually being purchased by Saint-Gobain who continue manufacturing under their Carborundum name today.

A semiconductor is a chemical compound that conducts electricity under certain circumstances and blocks it in others, much like copper wires conduct current while wood blocks it. Semiconductors can be designed to conduct or block current according to design, making them invaluable components in many electronics devices like diodes and transistors.
Silicon carbide is one of the most widely-used semiconducting materials. It is composed of elements from group 14 of the periodic table that have been combined together in crystal form; later these crystals can be cut into thin wafers for use in microelectronics and photovoltaic applications. Other forms of silicon carbide may include ternary compounds, oxides or alloys.
To understand how semiconductors operate, one must understand what a band gap is. Device physicists observe two energy bands: conduction band and valence band. Device physicists refer to this phenomenon as band-hopping; when cooling occurs electrons move from the valence band into conduction through an energy gap called band gap and onto conduction. When the device cools further electrons hop across through this band gap – known as band hopping.
Edward Goodrich Acheson is widely credited with discovering silicon carbide as a semiconducting material in 1891, sparking modern metallurgy by heating clay, powdered coke, and carbon in an electric furnace – this marked the first industrial scale production of silicon carbide ever possible – his company went on to produce over 10 million pounds annually by 1910; and was used both as an abrasive and for printing applications.
It is a lubricant
Lubricants are substances designed to reduce friction between two surfaces, such as metals. Lubricants come in liquid, solid or gaseous forms and may be liquid, solid, or gaseous. Lubricants also protect surfaces from corrosion or keep it clean; essential elements for smooth machine operation. There are many kinds of lubricants on the market such as oils and greases while others use natural ingredients; Carborundum is one such natural substance which has multiple applications in many situations.
Edward Goodrich Acheson made the discovery of carborundum during an attempt at creating artificial diamonds in 1891. While using an ordinary carbon arc light to heat a mixture of clay (aluminium silicate) and powdered coke, blue crystals formed which proved to be a new compound of carbon and aluminium he dubbed carborundum by Acheson.
This material is hard and durable, which makes it suitable for use in devices like grinding wheels and cutting tools, sandpaper, gritpaper, grip tape for skateboards, etc.
Carborundum can also be used as part of a printmaking technique known as carborundum collagraph printing, an intaglio form involving applying carborundum grit to plates to produce prints with vibrant hues and deep tones. Available as both powder and paint versions.
