鳞石英

The microstructure of crystallized cristobalite,tridymite andmelanophlogite have been studied and the effect of crystallization on sintering of compositealso has been discussed.

对所析出的方石英、鳞石英和硫方石英的显微结构进行了讨论，同时亦讨论了石英玻璃的析晶对复合材料烧结的影响。

A white or colorless vitreous insoluble solid; various forms occur widely in the earth's crust as quartz or cristobalite or tridymite or lechartelierite.

一种白色或无色的玻璃质不溶固体，以各种形式广泛存在于地壳中，如石英、方石英、鳞石英等。

On the gas face,there are tridymite,silicate,C3P,glass phase and also a few precipitated carbon.

燃烧面由鳞石英、硅酸盐、磷酸三钙、玻璃相和无定形碳组成，但沉积碳较少。

The ash from open-field burning or from non-controlled combustion in industrial furnaces usually contains a higher proportion of non-reactive silica minerals such as cristobalite and tridymite, and it should be ground to very fine particles to develop pozzolanic activity.

由开阔场地燃烧或在工业炉中不加控制地燃烧得到的灰通常含有较高比例的非反应性二氧化硅矿物质，例如方石英和鳞石英，而且，要发展火山灰活性，它应该被研磨成很细的颗粒。

SiO〓 crystal transformation was improved by adding Na〓SO〓, alpha cristobalite but not tridymite was catalytic active support. C〓 selectivity was improved by adding W and P, and suppressed deep oxidation property of SiO〓. W-O in catalyst surface was not active species. The support combined with S, W, P show low activity and high C〓 selectivity.

Na〓SO〓的加入促进了SiO〓晶型的转化，α-方石英是催化活性载体成分，而鳞石英没有甲烷氧化偶联反应活性。W和P的加入改善了C〓烃的选择性，抑制了SiO〓的深度氧化特性；W-O物种不是催化活性物种；由S、W、P及SiO〓组成的载体反应活性较差，但选择性较好；同时S元素对C〓烃的选择性的贡献有限。

On the coke face,the metacristobalite and Quartz transformed into tridymite completely.The C3P,pseudowollastonite and glassy were formed by absorbtion of MgO,Al2O3,P2O5,and CaO contained in coke.

炭化面亚稳方石英和残存石英几乎全部鳞石英化，吸收焦炭中的MgO、Al2O3、P2O5和CaO，生成磷酸三钙（C3P）、假硅灰石和玻璃相。

Glass batches of compositions in the tridymite,lithium metasilicate, lithium disilicate and spodumene primary phase regions of Li_2O—Al_2O_3—SiO_2 system were melted and crystallised.

取自鳞石英、偏硅酸锂、二硅酸锂和锂辉石4个相区的玻璃成分，经过熔制、析晶，并用X-射线衍射方法鉴定了析出的晶相。
