    2020-10-23 · Refractories are materials that provide linings for high-temperature furnaces and otherprocessing units. Refractories must be able to withstand physical wear, high temperatures (above538°C [1000°F]), and corrosion by chemical agents. There are two general classifications ofrefractories, clay and nonclay. The six-digit source classification code (SCC) for refractorymanufacturing is 3-05-005. Clay refractories are produced from fireclay (hydrous silicates ofaluminum) and alumina (57 to 87.5 percent). Other clay minerals used in the production ofrefractories include kaolin, bentonite, ball clay, and common clay. Nonclay refractories …
