What is dolomite or dolomite?
Dolomite is a mineral composed mainly of calcium and magnesium carbonate. It is widely used in industry due to its abundance in nature and its unique chemical composition. However, not all types of dolomite are the same. In this article, we will talk about the difference between raw dolomite, calcined dolomite, and sintered dolomite, and we will also talk about a new mineral generated by the dead calcination of dolomite called pericalse.
Raw Dolomite
Raw dolomite is the natural form of the mineral. It is extracted from quarries and mines and is used in the construction industry as fill material and to make concrete and asphalt. It is also used in agriculture as a source of magnesium and calcium for plants. Although raw dolomite is useful for certain applications, it is not suitable for others due to its composition and physical characteristics.
Calcined Dolomite CaMg(CO3)2
Calcined dolomite is produced by applying heat to raw dolomite up to 800ºC in a horizontal furnace. During the calcination process, dolomite loses part of its calcium-magnesium carbonate content and transforms into calcium-magnesium oxide. Calcined dolomite is used in the steel industry as an additive in steelmaking, as well as in the production of glass, ceramics, and refractories. It is also used in agriculture to adjust soil pH and improve crop quality.
Sintered Dolomite dolomite
Sintered dolomite, also known as dead-burned dolomite, is produced by high-temperature calcination of raw dolomite, between 1,400 and 1,800 degrees, in a vertical furnace. During this process, the dolomite completely breaks down and turns into pure calcium magnesium oxide. Sintered dolomite is a high-quality material with a wide range of applications in industry, including the manufacture of refractories, advanced ceramics, and specialty glass. It is also used in the production of abrasive materials and in the synthesis of chemical compounds.
Pericalse is a new mineral that is generated during this dead calcination process of dolomite. It is an oxide of calcium and magnesium with a unique crystalline structure that makes it useful for applications in the ceramic and advanced materials industry. Pericalse has high temperature resistance and is capable of withstanding high pressures, making it an ideal material for use in applications that require high strength and durability.
Summary
In summary, raw dolomite, calcined dolomite and sintered dolomite are very useful materials in industry. Each one has unique properties and is used in different applications. Pericalse, a new mineral generated during the dead calcination of dolomite, is an exciting addition to the field of materials science and has great potential for use in specialized applications in the future. We hope this information has been helpful in understanding the differences between these materials and how they are used in industry.
