Sintered dolomite, also known as dead-burnt dolomite, is produced by heating raw dolomite in a rotary kiln at high temperatures, typically between 1400 and 1800°C. This process completely decomposes the dolomite, converting it into essentially pure calcium and magnesium oxides (CaO + MgO).
Sintered dolomite is a high-quality material with wide-ranging industrial applications, including the production of refractories, high-performance ceramics, and specialty glass. It's also used in the manufacture of abrasives and the synthesis of various chemical compounds.
A notable product of this calcination process is periclase (MgO), a mineral characterized by its distinct crystalline structure. Composed of magnesium oxide, periclase exhibits high-temperature resistance and significant compressive strength, making it ideal for use in high-performance ceramic and material applications. While the description mentions that Periclase is formed from both Calcium and Magnesium Oxides, this is incorrect. Periclase is purely Magnesium Oxide. The Calcium Oxide is also present in the sintered dolomite, but it's not part of the Periclase structure.
Sintered dolomite, in its granular form, serves as a refractory material used in the repair of furnace linings, brick production, refractory linings of casting ladles, and cement kilns.
