silicon | Element, Atom, Properties, Uses, & Facts

When silicon and carbon are coined at electric furnace temperatures (2,000–2,600 °C [3,600–4,700 °F]), they form silicon carbide (carborundum, SiC), which is an important abrasive. With hydrogen, silicon forms a series of hydrides, the silanes. When coined with hydrocarbon groups, silicon forms a series of organic silicon compounds. Three stable isotopes of silicon are known: silicon-28, which makes up …

Tips on Sanding Wood Floors With an Aluminum Oxide Finish

With silicon carbide abrasives, the grain macro-fractures, meaning that before the grain can dull, it breaks into smaller pieces that essentially resharpen the abrasive. So, silicon carbide abrasives stay sharp until they die, but they die relatively quickly. That makes silicon carbide the least expensive option per belt price, but product life is shorter.

Silicon Carbide Formula - Silicon Carbide Uses, Properties

Silicon carbide, also known as carborundum, is a unique compound of carbon and silicon and is one of the hardest available materials. Formula and structure: The chemical formula of silicon carbide is SiC. Its molecular formula is CSi and its molar mass is 40.10 g/mol. It is a simple compound with the carbon atom attached to silicon through a triple bond, leaving both atoms with a positive and negative charge.

10 Interesting Facts About Titanium | Refractory Metals

10 Interesting Facts About Titanium. Titanium is a refractory metal that is widely used in surgical implants, automotive sun visors, aircraft bodies, and eyeglass frames. Although titanium has been discovered for many years, it still surprises people by its ubiquity in our lives without you realizing (yes it’s also in your body).

Carbides and Carbide Materials (hardmetals) Selection

Typically, SiC is used in the alpha silicon carbide structural form. Silicon carbide is a black, high-hardness ceramic that is usually harder than alumina. Depending on the addition of impurities SiC may be green or black in color. Fully-dense SiC can be transparent (moissanite). Silicon carbide is used in structural materials, astronomy, disc brakes, diesel particulate filters, cutting tools, and heating elements. High …
