Electro-Fused Magnesium Oxide
Tateho has improved the chemical stability and the electro insulating of DENMAG® the magnesium oxide by using the electro-fused method for the first time in Japan.
Features
Magnesium oxide that advances together with industries
In 1960, Tateho succeeded in the industrialization of electro-fused magnesium oxide for the first time in Japan.
Since then, by gaining expertise in our original electro-fusing operations, high temperature burning and techniques for controlling fine particles, Tateho has continued to provide a steady supply of electro-fused magnesium oxide which is a high-quality and high-purity.
Tateho calls the magnesium oxide obtained by burning of the magnesium hydroxide at high temperature "heavy-burned magnesium oxide." Its crystal grain is large, and its stability is excellent.
Our electro-fused magnesium oxide is produced by crushing big crystals formed by electro-fusing method. So our electro-fused magnesium oxide is exceeds the specifications of heavy-burned magnesium oxide in chemical stability, moisture resistance and electrical insulation.
Electro-fused magnesium oxide is used for insulating fillers and refractories.
Features and Usages of Grades
| Grades | Features | Usages |
|---|---|---|
| DENMAG®️ SSP#3 | This grade has the highest purity among electro-fused magnesium oxides. It is highly suitable for atomic energy usages in which reliability is essential. | • Electrical insulating materials for atomic energy usages • Raw materials for high purity magnesium oxide ceramics |
| DENMAG®️ KMA-X | This grade has the largest particle size among electro-fused magnesium oxides. It is suitable for refractory raw materials. | Raw materials for high-level basic refractories (MgO- carbon bricks, ramming mix, and continuous casting refractories) |
| DENMAG®️ KMAO-H | This is a standard grade among electro fused magnesium oxides. This grade has comparatively small particle size among electro-fused magnesium oxides. It is suitable for insulating materials. | • Electrical insulating materials • Raw material for magnesium oxide ceramics • Raw material for automotive brakes |
| DENMAG®️ KMAOH-F | The particle size of this grade is smaller than that of DENMAG® KMAO-H. This grade is suitable for usages in which packability is necessary. | • Raw material for Insulators • Raw material of magnesium oxide ceramics • Raw material for automotive brakes |
