Powder of high-purity magnesium hydroxide, PUREMAG®︎FNM-HS produced by Tateho Chemical

PUREMAG®️FNM-HS

High-purity Magnesium Hydroxide

Magnesium hydroxide having a purity of 99.9% or more

summary

Features

Tateho developed the PUREMAG® FNM-HS high-purity magnesium hydroxide that is no less than 99.99 percent pure, by employing aspecial processing technology.
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.

1. High purity
This high-purity product contains the magnesium hydroxide at not less than 99.9 percent purity, with hardly any impurities.
It has the highest purity among commercially available magnesium hydroxide.
2. High dispersibility
The primary particle is monodispersed character particle of submicron size, with excellent dispersibility.

About PUREMAG® FNM-HS 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.
