Silicon – expert written, user friendly …

Silicon can enhance iron’s magnetic properties; it is also an important component of steel, which it toughens. Silicon carbide, more commonly called carborundum, is extremely hard and is used in abrasives. Silica (SiO 2) in sand and minerals in clay is used to make concrete and bricks. Silica, as sand, is also the main constituent of glass.

Silicon Carbide has very good mechanical properties and maintains its strength even at extremely high temperatures. It also has excellent resistance to acids, alkalis and molten salts up to 800°C. These exceptional properties make SiC suitable in appliions requiring great resistance to wear, thermal shock and corrosion. Top Seiko has

Silicon carbide | chemical compound | …

Silicon carbide, exceedingly hard, synthetically produced crystalline compound of silicon and carbon. Its chemical formula is SiC. Since the late 19th century silicon carbide has been an important material for sandpapers, grinding wheels, and cutting tools. More recently, it has found appliion in refractory linings and heating elements for

What is GaN? - EPC

Gallium nitride crystals can be grown on a variety of substrates, including sapphire, silicon carbide (SiC) and silicon (Si). By growing a GaN epi layer on top of silicon, the existing silicon manufacturing infrastructure can be used eliminating the need for costly specialized production sites and leveraging readily available large diameter silicon wafers at low cost.
