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.

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。

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。

It has high SiO2,low flux (AL2O3+2R2O),low Fe2O3,high refractoriness under load, low true density,low residual quartz,high tridymite and cristobalite.

该产 品具有SiO2含量高,熔融指数(AL2O3+2R2O)低、Fe2O3含量少,荷重软化点高、真密度小、低含量残余石英、方、磷石英含量高等特性。

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。

Adding fused MnO2-CaF2 Mineralizer into fine silicon powder can change its cryst al structure and improve the amount of tridymite,thus can improve the kiln furni ture's high temperature properties and prolong its lifetime.

MnO2-CaF2混合矿化剂能改善硅微粉析晶结构,增加磷石英的含量,从而改善窑具的高温性能,延长使用寿命;采用XRD法测定析晶结构,并测定窑具的抗折强度、抗折强度保持率、气孔率、吸水率等各项性能指标,综合分析得出MnO2-CaF2混合矿化剂的最佳加入量为2%。
