Carborundum Company | Encyclopedia

Indeed, silicon carbide ’ s abrasive and refractory qualities played a vital role in the growth of modern industry. Carborundum expanded rapidly. In 1905 it introduced a new abrasive, fused aluminum oxide, under the name Aloxite. At the same time, the company developed a process for producing fused silicon metal.

Refractory | industrial material | Britannica

Among the clay-based refractories are fireclay, high-alumina, and mullite ceramics. There is a wide range of nonclay refractories, including basic, extra-high alumina, silica, silicon carbide, and zircon materials. Most clay-based products are processed in a manner similar to other traditional ceramics such as structural clay products; e.g
