Light burned magnesium oxide for industries

Feature

The light burned magnesium oxide is obtained by burning the magnesium hydroxide at the low temperature.
Its particle is small, and its reactivity is excellent.
The light burned magnesium oxide is used as the surface treatment agent and the ceramic raw material.
Tateho's light burned magnesium oxide is produced by using the accumulated burning technology from a variety of raw materials.
In particular, when you use our light burned magnesium oxide as the annealing separator of electrical steel sheet, electrical steel sheets obtains the electro magnetic property of the highest quality in the world.
We produce the magnesium oxide that has the reactivity, particle size and purity so that we may satisfy a wide demand of the customer.

"Tateho's vision of creating new environment-friendly materials"

Tateho Chemical Industries Co., Ltd. was born in the town of Ako--an area blessed with a warm climate and the abundant marine resources of the Inland Sea of Japan.
The history of the salt industry in Ako is long--dating back nearly 1300 years to the Nara period.
In 1966, Tateho was established as a group of engineers seeking to provide new materials widely useful for society by putting this inherited, time-honored wisdom into full use, and by effectively utilizing bittern, a substance left after separating salt from seawater.
Since then, we have continued to provide the world with highly functional products--including magnesium oxide, magnesium hydroxide, electrofused magnesium oxide, single crystal magnesium oxide, flame retardants, and ceramics--by expanding our businesses on the basis of our proprietary crystallization control technology.
We are committed to contributing to industry worldwide under the slogan of "Aiming to be a development-oriented company friendly to the natural environment and leading the world with proprietary technologies" by continuously adhering to our environmental policy and further improving our proprietary technologies.
