The practice showed that the blast furnace slags mainly consisted of melilite,cuspidine,bivalent metallic sulphide and Ce-Ca silica.

黄、枪晶、二价金属硫化物、铈钙硅是构渣主矿物。

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.

黄结构参数，按其化学分是在钙铝黄和镁黄之间变化，黄作为原始矿物相在碱性矿渣中比较罕见。
