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，是生产高级碱性砖和不定型耐火材料的理想材料.

 

It is produced by light burning , fine grinding ,dry ball indentation and ssintering in extra high temperature oil shaft kiln with superior magnesite as raw material . With MgO content over 97%,low impurity content , direct combination of perclase cryatal body aw we;:as firm and tight structure , it is an ideal raw material to produce high-class basic bricks and unshaped refractory materials.
