Star Grace Magnesium Oxide Powder 90%, can be used in abrasive stones. As the owner of magnesite, we have the best quality ore with low SiO2 and CaO content to calcine MgO powder, which is suitable to use in manufacture abrasive stones and flour grinding wheels. In the production, low CaO can make the stones hard. Low SiO2 can make the stones smooth. And moderate LOI can shorten the setting time.
Magnesium oxide is a main raw material, which is added in magnesium chloride solution to produce magnesium oxychloride cement (MOC cement). Due to high bonding strength, MOC cement is largely used in the manufacture of grinding and polishing stones. The main end-users are the marble, granite and mosaic processing industries.
