    Multiple issues orphan August 2010 unreferenced July 2010 Acid brick or acid resistant brick is a specially made form of masonry brick that is chemically resistant and thermally durable . Acid brick is created from high silica shale and fired at higher temperatures than those used for conventional brick. Some manufacturers create the brick by baking it for over a week. It has an average compressive strength of approximately 23,000 PSI. The ASTM International ASTM specification C 279 creates specifications for acid brick properties. Acid brick is not resistant against hydrofluoric acid or strong alkali . Varieties Acid brick comes in multiple varieties. The most frequently used variety is red shale .

    Acid maceration is a technique to extract organic matter organic microfossil s from a surrounding rock geology rock matrix geology matrix using acid . Hydrochloric acid or acetic acid may be used to extract phosphatic fossil s, such as the small shelly fossil s, from a carbonate matrix. Hydrofluoric acid is also used in acid macerations to extract organic fossils from silicate rocks.

  1. Mineral acid

    Acids and bases A mineral acid or inorganic acid is an acid derived from one or more inorganic chemistry inorganic compounds. A mineral acid is not organic and all mineral acids release hydrogen ions when dissolved in water. Characteristics Commonly used mineral acids are sulfuric acid , hydrochloric acid and nitric acid They are also known as bench acids . Mineral acids range from acids of great strength example sulfuric acid to very weak boric acid . Mineral acids tend to be very soluble in water and insoluble in organic solvents. Mineral acids are used in many sectors of the chemical industry as feedstocks for the synthesis of other chemicals, both organic and inorganic. Large quantities of these acids, especially sulfuric acid, nitric acid and hydrochloric acid are manufactured for commercial use in large plants. Mineral acids are also used directly for their corrosive properties. For example, a dilute solution of hydrochloric acid is used for removing the deposits from the inside of boilers, with precautions taken to prevent the corrosion of the boiler by the acid. This process is known as descaling.
