melilite

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、铈钙硅石构成高炉的主要矿。

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，按其学成分在钙铝黄长石和镁黄长石之间变，黄长石作为原始矿相在碱性矿较罕见。
