Our magnesium oxides are produced from carefully selected magnesium hydroxides using our sophisticated sintering technology to its fullest advantage. We offer a full lineup of products for a variety of applications in order to meet the diverse needs of many fields of industry.Major applications include electromagnetic steel plate surface treatment agents, materials for electronic parts and components, such as capacitors, and chemicals (reagents) used in laboratories. An electromagnetic steel plate surface treatment agent, the major application of magnesium oxide, is applied on the surface of an electromagnetic steel plate used in transformers to create a ceramic insulating film and to reduce the loss of electrical energy (known as iron loss). Magnesium oxide powder for this application is difficult to manufacture but the high-performance magnesium oxide we developed enables us to produce a smaller transformer that is both quiet and environmentally friendly. At present, our magnesium oxides, as an energy-saving product, are used in nearly half of the large transformers in use worldwide.High-purity magnesium oxide (RSG) is produced from carefully selected material using a special refining process. Because impurities are totally controlled, the product comes up to the JIS Reagent Special Grade Standard K8432. Our high-purity magnesium oxide can be used in a wide variety of applications ranging from reagents to electronic components in which a high-purity material must be used.
