PUREMAG®️ FNM-G

High Purity Magnesium Oxide

Magnesium oxide which achieved 99.99% ultra-high purity by liquid phase method for the first time in Japan.

summary

Features

Tateho developed the "PUREMAG® FNM-G" high-purity magnesium oxide that is no less than 99.99 percent pure for the first time in Japan, by employing a special processing technology in liquid phase.

Because it contains hardly any impurities, it can be used for high-purity applications like electronic materials, phosphor raw materials, catalyst materials, and various additives, etc. as necessary in various wide-ranging usages.

Four Nine Purity Magnesium Oxide Powder

1. High purity
This high-purity product contains the magnesium oxide at not less than 99.99 percent purity, with hardly any impurities. It is the highest purity product among commercially available magnesium oxide.

2. High dispersibility
The primary particle is monodispersed character particle of submicron size, with excellent dispersibility.

About PUREMAG® FNM-G Particle Size

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