Feb 06, 2001 · Deadburned magnesia, which is produced in shaft and rotary kilns at temperatures over 1500 o C, has reduced chemical reactivity therefore is more suited to refractory appliions. Fused magnesia is used for a variety of refractory and electrical appliions.
Effect of Hydration in Magnesia Based Refractories for
to the original magnesia. Generally, magnesia used in lime kiln refractory is either of dead burnt or fused type, which is produced from natural magnesite (MgCO 3) or extracted from sea water. The physical and chemical properties of magnesia based refractories are more complied than those of pure magnesia due to different level of
Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). It has an empirical formula of Mg O and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding .
Process for the production of dead burned refractory magnesia
Jan 06, 1981 · The magnesium hydroxide filter cake obtained by pressure filtration can be directly dead burned to refractory magnesia. This process has the disadvantage of yielding granular dead burned magnesia having a density of only about 3.2 to about 3.35 grams per cubic centimeter (g/cc), depending upon the impurities in the initial starting material.
Sintered magnesia (MgO i.e., dead burned magnesia: DBM) is produced through a sinter burning process at C temperature ranges of 1600 to 2200 Different types are defined by the content of lime in the raw material, which is in the range of <2 to 35% and the SiO2 content, which in

Appliion of cleaner production in a Chinese magnesia
Magnesia is the basic raw material of refractory products such as magnesia brick. It is generally divided into three egories, according to the sintering temperature used: caustic calcined magnesia (CCM), dead burned magnesia (DBM), and fused magnesia (FM) (Quan, 2008, Yin and Feng, 2008, Yin et al., 2010). However, due to disordered resource

Magnesium (Mg) is the eighth most abundant element and constitutes about 2% of the Earth''s crust, and it is the third most plentiful element dissolved in seawater. Although magnesium is found in over 60 minerals, only dolomite, magnesite, brucite, carnallite, and olivine are of commercial importance. Magnesium and other magnesium compounds are also produced from seawater,

Manufacture of magnesium oxide from sea water by Premier
The term periclase refers to natural magnesium oxide. In 1979, Premier Periclase established a plant to manufacture magnesium oxide using sea water as the source of magnesium. The process involves formation of a magnesium compound from the reaction of dissolved magnesium salts in sea water with calcium hydroxide, followed by further reactions.
In addition, the type of process (batch or continuous) and the uses of the product(s) must be identified. One of the case studies is concerned with the manufacture of magnesium oxide from sea water. This process is carried out by Premier Periclase in Drogheda, Co. Louth. The term periclase refers to natural magnesium oxide. In 1979, Premier
