It`s made from periclasite,magnesite aluminium spinel,chrome ore as raw material.

以方镁石、镁铝尖晶石、铬矿为主晶相中性耐火。

The exoplanet's atmosphere condenses out minerals such as enstatite, corundum, spinel, and wollastonite.

颗系外行星气冷凝后产生矿物，如：顽火辉石、刚玉、尖晶石硅灰石。

The development and application of raw minerals and products of spinels are also briefly introduced.

尖晶石其它应用，如尖晶石轴承及颜料等也取得了发展。

From all possible members of the spinel groups， hercynite and galaxite， were found to be the most efficient.

在所有可能尖晶石矿族成员中，铁铝尖晶石锰铝尖晶石被发现是最有效(添加剂)。

The composition, technique and characters about the manganite based NTC thermistor materials were reviewed in this paper.

摘要本文对含锰尖晶石系列热敏电阻材料组成、备工艺性能给予了评述。
