该砂是适用高级菱镁石或高级轻烧镁粉为制造原原材料在电弧放电炉中较耐高温度熔融而成。方镁石健康改善、尖晶石大、真接运用率高、结构设计高密度、抗渣性强、较耐高温度质量分数保持稳定得天独厚。是生產镁碳砖、含碱砖和不塑形耐火原材料的良好的制造原原材料,按MgO分子量96-98%分定级。lt is produced by fusion in the electric are furnace with high temperature with superior magnesite or superior light burned magnesite powder as raw materials. Periclase develops completely and its crystal is big.with high combination rate, firm and tight structure, good refuses resistance and stable,good high temperature volume. lt is good raw material to produce magnesia carbon bricks,high-class magnesia bricks and unshaped refractory materials.Grades are classified according to MgO content 96%-98%.
