晶石

In 1985, gem spinel of extreme beauty and size was discovered at Pamir Mtns., which is considered as the locality of "one of the kind" museum piece spinels in the world.

照片上大而美丽、近乎完美的尖晶石是1985年在帕米尔山脉发现的。世界各地的博物馆中，可供参观的宝石级的尖晶石大都是产自帕米尔地区。

The variety of synthetic gemstone includes synthetic titanic schorl, titanate, YAG, rolled gallium garnet, synthetic cubic diocroma, synthetic sapphire, synthetic spinel, synthetic titanic schorl, synthetic alexandrite, synthetic diamond, synthetic emerald, synthetic bleak and synthetic quartze.

合成宝石种类包括（合成金红石、钛酸锶、钇铝榴石、轧镓榴石、合成立方锆石、合成蓝宝石、合成尖晶石、合成金红石、合成变石、合成钻石、合成祖母绿、合成欧泊、合成石英）。

Andalusite is a polymorph with two other minerals, Kyanite and Sillimanite.

红柱石属多晶型物，含蓝晶石和硅线石两种不同矿物。

The low-pressure andalusite sequence metamorphic belt includes biotite zone, garnet zone, staurolite zone, staurolite-andalusite zone, sillimanite zone and cordierite-sillimanite zone. It is calculated that the P-T conditions are 445～550℃, 0.2～0.6GPa for biotite zone, 480～566℃, 0.54± 0.22GPa for the garnet zone, 601±20℃, 0.8±0.25GPa for the staurolite zone, 540±20℃, 0.32± 0.05GPa for the staurolite-andalusite zone, 640℃, 0.43GPa for sillimanite zone, 740～800℃, 0.4～0.7GPa for the cordierite-sillimanite zone.

黑云母带的变质条件估计在445～550℃、压力在0.2～0.6GPa范围变化；石榴石带温度在480～566℃、压力在0.54±0.22GPa的范围；十字石带范围为601±20℃、0.8±0.25GPa；十字石-红柱石带为540±20℃、0.32±0.05GPa，而利632.4℃、0.785GPa，这个值不是红柱石的稳定范围，这可能是其早期中压变质条件；矽线石带的条件640℃、0.43GPa左右，由于其石榴石中有蓝晶石包体，因此其早期也可能有中压条件的变质；堇青石-夕线石带范围大致为740～800℃、0.4～0.7GPa之间。

They are important components of many metamorphic and ignious rocks.

工业上应用较多的主要是镁铝尖晶石和镁铬尖晶石。

The phase constitutions of Magnesia-based dry vibratable materials is designed by the analysis of phase equilibrium digrams, in which the periclase is host crystalline phase, the Spinel, Forsterite and Monticellite et al are the bonding phase in matrix.

本文通过相图分析设计了镁质干式振动料的物相组成，其主晶相为方镁石，基质为镁橄榄石、尖晶石及少量的钙镁橄榄石等。

The experiment results showed that MnO〓 and TiO〓 could accelerate the sintering reaction of the NiFe〓O〓 spinel, improve the density and the intensity of the spinel ceramic, and drop the sintering temperature as well.

研究结果表明，添加MnO〓和TiO〓可以促进尖晶石陶瓷相的烧结，提高尖晶石的密度和强度，降低烧结温度。

The wolframite, scheelite, tantalum niobite and fine spar have uneven distribution in the raw ores. Relatively, the wolframite and scheelite have coarse embedded granularity, generally 0.8 ~ 0.04 mm. The tantalum niobite and fine spar have fine embedded granularity, generally 0.2 to 0.04 mm.

原矿中黑钨矿、白钨矿、钽铌铁矿、细晶石的嵌布粒度皆为不均匀嵌布，黑钨矿与白钨矿的嵌布粒度相对较粗，一般为0.8~0.04毫米，而钽铌铁矿及细晶石的嵌布粒度则很细，一般为0.2~0.04毫米。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.
