PHYSICAL PROPERTIES
Magnesium oxide (MgO), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium . It has an empirical formula of MgO.Pure MgO is not conductive and has a high resistance to electric current at room temperature.
APPLICATION
MgO is widely used in rubber (tire, cable, conveyor belt, synchronous belt, triangle belt, rubber tube, rubber plate, rubber roller, seal, rubber plug, etc.), adhesive, friction materials, organic magnesium salts, electronic components, catalysts, ceramics, glass fiber reinforced plastic, dye, medicine, national defense and other industries.
