1.1 This specification covers machine made solid uncored carbon brick produced from either metallurgical or petroleum calcined coke, baked to a minimum 1850°F (1010°C), and suitable for use in masonry construction which will be exposed to various chemicals. These units are designed primarily for industries using hydrofluoric acid, fluoride salts, and high concentrations of alkalies such as sodium and potassium hydroxide. Carbon brick are normally used with carbon filled chemical-resistant mortars.

TABLE 1 General Guide to Chemical Resistance of Carbon Brick
Note 1This table is intended for use as a general guide to the resistance of carbon brick in immersion service at ambient temperatures. Specific recommendations should be obtained from the carbon brick manufacturer. Carbon brick can be used to 650°F (340°C). Over 650°F (340°C), strict environmental control is paramount to ensure that the environment is non-oxidizing.
