堇青石

Cordierite ceramics with low dielectric constant and loss were developed.

用溶胶-凝胶法制备了低介低烧堇青石陶瓷材料。

The cordierite glass-ceramics were prepared using high alumina fly ash as the main raw material.

以高铝粉煤灰为主要原料，制备了堇青石微晶玻璃。

Our products include 95~99.9 Al2O3, ZrO2, ZTA as well as steatite, cordierite and so on.

产品涵盖了95~99.9氧化铝以及氧化锆、ZTA、滑石瓷、堇青石等陶瓷材料产品，广泛应用于航空航天、化工、机械、汽车、电子和纺织等领域。

When the temperature reaches 900℃, the layer structure of montmorillontite is destroyed, and the new mineral phase μ-cordierite is found.

当温度达到900℃时，蒙脱石的层状结构完全被破坏，并有新的矿物相μ-堇青石产生，当温度为1200℃时，则出现方英石及莫来石相。

A deep blue cordierite often used as a gemstone.

一种深蓝色的堇青石，用作宝石。

A dichroic violet - blue to gray mineral silicate of magnesium,aluminum,and sometimes iron.

堇青石一种呈介于紫蓝于灰色的二色性矿物，是含镁、铝、有的也含铁的硅酸盐

The crystallization rate of Mg-petalite increases with high ZrO〓/TiO〓 proportion.β-Quartz solid solution, cristobalite, zircon,α-cordierite and enstatite appear successively at high temperature.

随后玻璃中先后析出假蓝宝石相、β-石英固溶体、方石英、锆英石、α-堇青石和顽火辉石相。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
