melilite

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

黄长、枪、价金属硫化物、铈钙硅构成高炉渣的主要矿物。

2.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.

黄长的结构参数，按其化学成分在钙铝黄长和镁黄长之间变化，黄长作为原始矿物相在碱性矿渣中比较罕见。
