Zirconium oxide resistant to molten steel This is a type of zirconium oxide that, through use of the electrofusion method, has improved corrosion resistance to molten steel.

Electrofused zirconium oxide for industries

Tateho Chemical Industries Co., Ltd. supplies unstabilized ZIRFUSE®FZ-H and partially stabilized ZIRFUSE® FZCA with calcium oxide added as stabilizer.
Manufactured using our own electrofusion technology, our zirconium dioxide ZIRFUSE® is characterized by large crystal grains and excel in corrosion resistance to molten steel.
With low silica content, our zirconium dioxide exhibits less reactivity with electronic parts, and has such applications as floor plates used in sintering electronic parts.
Tateho has a large assortment of products in various grain sizes, large and small, to respond readily to extensive customer requirements.

"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.
