Products Description
Similar to the production of lime, magnesite can be burned in the presence of charcoal to produce magnesium oxide, which takes the form of the mineral known as perlite. Large quantities of magnesite are burned to produce magnesium oxide: an important refractory material used as a lining for blast furnaces, kilns and incinerators. The calcination temperature determines the reactivity of the resulting oxide product, and the classification of light-fired and heavy-fired refers to the surface area of the product and the resulting reactivity, which is usually determined by the industry standard iodine number. A "light burn" product generally refers to calcination from 450 °C with an upper limit of 900 °C, which produces good surface area and reactivity. Above 900 °C, the material loses its reactive crystalline structure and reverts to a chemically inert 'dead burnt' product - more desirable for refractory materials such as furnace linings.
DBM is a chemical compound, that means when magnesite is calcined at 1800 °C, carbon dioxide escapes completely and magnesium oxide forms a dense mass of cubic magnesite.
