Magnesium oxide TOP > Ceramic > High purity magnesium oxide ceramic products


Taking on the challenges of new materials!! New items of ceramics provide aid to developers Made of 99.99%-pure magnesium oxide, the products are high-purity ceramics with less impurity mixture.

Using as raw material PUREMAG®FNM-G, high-purity magnesium oxide it had developed on its own, Tateho Chemical Industries Co., Ltd. came up with saggers and crucibles of high-purity magnesium oxide.

TATECERA CMGH

Feature

With the highest melting point (3098K) among the oxides, Magnesium oxide excels in thermal conductivity (60W・m-1・K-1)and electric insulation (1014 Ω); this enables its use as a refractory under severe conditions.
In particular, magnesium oxide excels in corrosion resistance to molten metals is compatible with more metals than aluminum oxide is; these form features of magnesium oxide.
Additionally, the introduction of impurities from the crucible can be reduced by using a crucible made of magnesium oxide with 99.99% purity (hence fewer impurities).
Furthermore, as a substantia compacta it features impenetrability to vapor and the like.
*Tateho is glad to receive an order, even for a single item.

"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.
