Title:

マグネシア(MgO)を製造するための改良された方法

Document Type and Number:

Japanese Patent JP5102780

Kind Code:

B2

Abstract:

The process provides for the preparation of MgO from the reaction of magnesium salt and alkali/lime. The crude Mg(OH)2 is directly calcined and then treated with water to disintegrate the mass spontaneously to yield a slurry and dissolve away the soluble salts. This slurry is much easier to filter and wash than the original Mg(OH)2 slurry, which helps to speed up the purification operation and also conserve fresh water. Another important advantage of the present method is that even pasty or dough like reaction products that are processed using dough mixers and similar equipment can be worked up with ease. There is no compromise in the quality of MgO achieved in this manner.
