Inclusions in the gray strip defects consist of MgO and trace melilite,which result from MgO-C refractory in slag line. 灰色条带状缺陷中外来物主要为氧化镁,并含少量黄长石,来源于渣线镁碳砖耐火材料;
The foreign inclusions in the black strip defects mainly consist of melilite,MgAl2O4 spinel and trace of the perovskite resulting from ladle slag. 黑色条带状缺陷中外来物主要为镁铝尖晶石和黄长石,并有少量钙钛矿,来源于钢包渣;
The practice showed that the blast furnace slags mainly consisted of melilite,cuspidine,bivalent metallic sulphide and Ce-Ca silica. 结果表明:黄长石、枪晶石、二价金属硫化物、铈钙硅石是构成高炉渣的主要矿物。
Depending on the chemical composition the structural parameters of the melilite vary in the range between gehlenite and mernite.Melilitic separation and melilite as a primary phase are very rare. 黄长石的结构参数，按其化学成分是在钙铝黄长石和镁黄长石之间变化，黄长石作为原始矿物相在碱性矿渣中比较罕见。
