Powder of highly-dispersive magnesium oxide, DISPERMAG® produced by Tateho Chemical


Highly-Dispersive Magnesium Oxide

Magnesium oxide has features as high purity (99.9%) and high dispersibility.



Tateho has developed DISPERMAG® Highly-Dispersive Magnesium Oxide with our original technology. DISPERMAG® has a magnesium oxide purity of 99.9% and high dispersibility. So it is the most suitable magnesium oxide as a raw material for electronic materials. Besides an application for electronic materials, it can be used for a wide range of applications such as optical materials, catalyst materials and various additives.

Highly-Dispersive MgO Suitable for Electronic Materials

1. High Purity (99.9%)

The magnesium oxide purity of DISPERMAG® is 99.9% and it hardly contains metallic impurities.

2. High Dispersibility

DISPERMAG® exhibits high dispersibility in mixing with solvents or other powders.

DISPERMAG®, additives for MLCCs

DISPERMAG<sup>®</sup>, additives for MLCCs
DISPERMAG® is a submicron particle powder with a purity of 99.9%, and is the most dispersible powder in our magnesium oxide lineup.
The raw materials are required to have finer particles because of the recent trend toward smaller, thinner, and larger capacities in electronic devices.
DISPERMAG® is the best magnesium oxide additive for MLCCs (Multilayer Ceramic Capacitors) because of its ability to uniformly disperse fine primary particles.
