Abstract
Ceramic construction materials for chemical processes consist of two categories of materials, acidproof brick (red shale and fireclay) and specialty materials (silica, silicon carbide, high alumina, etc.). These materials are also known as chemical-resistant masonry. They are used in chemical environments because of their ability to withstand corrosion under severe service conditions. Red shale and fireclay materials are generally considered suitable for use with inorganic acids such as hcl, hno3, h2so4, and h3po4 in salt solutions and in mildly alkaline solutions. Specialty materials such as silica, silicon carbide (sic), and high alumina are used in applications where high temperature, wear, or chemical compatibility is important. Although these and other specialty materials exist, all have a higher cost than acidproof brick that limits their usage to extremely severe service applications. Depending on the use, ceramic construction materials should be evaluated in an environment simulating actual use conditions.
