Since the late 19th century silicon carbide has been an important material for sandpapers, grinding wheels, and cutting tools.

Such properties as high purity, strength and corrosion resistance make them suitable for process tubes for semiconductor heat-treatment furnaces, liner tubes, boats and paddles. In addition, we use the CVD method to offer a highgrade product coated with super high purity, fine silicon carbide, making it suitable for a wide range of customer requirements.

In recent years silicon carbide, SiC, has re-emerged as a vital technological material that is crucial in many materials and engineering applications. Interestingly, SiC is one of the few minerals that were first created synthetically and subsequently discovered in nature. It was first artificially synthesized in 1891 by Edward Acheson as a result of unexpectedly discovering small black crystals of SiC in an electrically heated melt of carbon and alumina. The subsequent refinement of this technique (the so-called Acheson process) led to the commercial production of large volumes of small SiC crystals (ground into powder form) for use as an industrial abrasive. In 1905, silicon carbide was observed in its natural form by the Nobel-prize-winning chemist Henri Moissan in Diablo Canyon, Arizona. The transparent mineral, now known as moissanite, is almost as brilliant and as hard as diamond, and is therefore often used as a gemstone. To date, no large natural deposits of SiC have ever been found in nature so all SiC used today is synthetic.

In the present day, SiC is one of the most widely used materials that plays a critical role in industries such as: aerospace, electronics, industrial furnaces and wear-resistant mechanical parts among others. Although SiC is widely used in electronics and other high technology applications, the metallurgical, abrasive, and refractory industries are dominating by volume.
