It is a product that has been refined and concentrated from magnesium hydroxide slurry, dehydrated, dried, calcined, shaped, and then subjected to high-temperature firing (over 1800°C) in a rotary kiln.
Based on our unique seawater treatment technology, we successfully manufactured the "seawater magnesia clinker" for the first time in post-war Japan, and we have now become the only manufacturer in the country. It is used in basic refractory raw materials, as well as in building materials and welding rod materials. 【Examples of Uses】 Basic refractory brick raw materials (magnesia bricks, spinel brick raw materials, etc.), Unformed refractory raw materials (stamping materials for electric furnaces, spraying materials, etc.), Electro-fused magnesia raw materials, Synthetic spinel raw materials, welding rod raw materials, Building materials raw materials.

Ube Materials Corporation is a manufacturer of specialty inorganic materials based in Ube City, Yamaguchi Prefecture. Using limestone, which is abundantly produced in Mine City, as raw material, the company produces calcium-related products such as quicklime and hydrated lime, as well as extracting magnesium from seawater using quicklime as a raw material to manufacture products like magnesium hydroxide and magnesia clinker (refractory material). Additionally, as a unique business, the company has developed a healthcare division that directly serves consumers by selling lime as a dehumidifying agent, and now offers products such as toothpaste, bath cosmetics, and other cosmetics through co-ops, mass retailers, mail order, and online sales.
