Slake-resistant calcium oxide This is a kind of calcium oxide whose slake-resistance is improved by means of the electrofusion method.

calcium oxide for industries

Using its unique electrofusing technology, Tateho Chemical Industries Co., Ltd. has succeeded in producing compact, high-purity calcium oxide by having lime crystal grains grow.
Our calcium oxide therefore has excellent slake-resistance.
In addition, its greater thermal shock resistance than that of magnesium oxide, enables use of our calcium oxide in long-life refractory lining and similar materials.
Recently, crucibles made from electrofused calcium oxide are used to melt special metals, such as titanium alloy, in order to remove impurities.

"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.
