Magnesia Division

Division Overview

At the Magnesia Division, we handle various magnesia-related products based on "Magnesium Hydroxide", which is derived from quicklime calcined at the Mine Plant and seawater taken by the Ube Plant.

We supply magnesium hydroxide used in flue gas desulfurization for pollution prevention, magnesia clinker that meets the needs of steel and refractory products industries in and outside Japan as a basic refractory material, and magnesium oxide used across various fields.

Recently, we have also focused on thermal-conductive MgO filler that improves resin heat dissipation, and environmental products.

We will continue developing and producing various new materials using our proprietary technology while maintaining harmony with nature and the environment.
