PUREMAG®

HIGH PURITY MAGNESIUM OXIDE POWDER PUREMAG® FNM-G

Feature

Tateho Chemical Industries Co., Ltd. developed the high purity magnesium oxide "PUREMAG®FNM-G" that contain not less than 99.99 percent by using the raw material selected carefully, and using a special processing technology.
Because it hardly contains impurities, it is possible to use it for high purity like an electronic material, a phosphor raw material, a catalyst material, and various additives, etc. necessary, various usages widely.

  1. High purity
    It is a high purity product that contain the magnesium oxide not less than 99.99 percent ,and impurities are hardly contained.
  2. High dispersibility
    The primary particle is monodispersed character particle of submicron.
    And, it is very excellent in the dispersibility.

About "PUREMAG®FNM-G" particle size

To facilitate handling, we process the granulation to secondary particle (A) of about ten microns and offer this product.
However, this product easily disperses to primary particle (B) of submicron when stirring it in the solvent.
Therefore, this product can be used as a magnesium oxide particulate of the high purity and high dispersion.

"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.
