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

黄长石、枪晶石、二价金属硫化、铈钙硅石炉渣的主要。

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.

黄长石的结参数，按其化学分在钙铝黄长石和镁黄长石之间变化，黄长石作为原相在碱性渣中比较罕见。
