高纯镁砂High Purity Magnesite

该砂是选用特级菱镁石经轻烧、细磨、干法压球、超高温油竖窑烧结而成。MgO含量大于97%，杂质含量低、方镁石晶体呈直接结合，结构致密，是生产碱性砖和不定型耐火材料的理想材料。

It is produced by light burn-ing, fine grinding, dry ball indenta-tion and sintering in extra high temperature oil shaft kiln with su-perior magnesite as raw material.With MgO content over 97%, low impurity content,direct combination of periclase crystal as well as firm and tight structure. It is anideal raw materil to produce high-class magnesia bricks and unshaped refractory materials.
