Active magnesium oxide, molecular formula MgO style, relative molecular mass of 40.30.Its chemical composition and physical form index and magnesium oxide are not much different from ordinary.But part of active magnesium oxide index is different from ordinary magnesium oxide requirements: such as to have appropriate particle size distribution, the average particle size less than 2 microns (2000 nm);Microscopic morphology of irregular particles or nearly spherical particles or flake crystal;With citric acid active (CAA) labeled activity for 12-25 s higher (the smaller the value activity);With iodine absorption value indicates that the activity of 80-120 - s (mg/I2) / 100 g (MgO style);Specific surface area between 5-20 m3 / g, depending on the specific volume between 6-8.5 mL/g.In addition, due to the high activity of magnesium oxide, easily absorbing water, sometimes the need for chemical processing to protect it.

 

Active magnesium oxide can be used as a neoprene and fluorine rubber accelerator and activator, used in adhesives, plastic, paint and paper packing;On medicine, active magnesium oxide used as antacids and sugar-refining, used for heartburn and duodenal ulcer disease;Also can be used as ceramic, glass, high thermal insulation material, magnesium oxide cement raw materials, etc.Active MgO style, moreover, the larger specific surface area, chemical activity, physical adsorption ability, good sintering performance, is the preparation of high functional fine inorganic material, electronic components, printing ink, the important raw material for harmful gas adsorbent.
