The result showed agglomeration temperature of nepheline was higher than of felspar adding a mensurable quartz could distinctly affect agglomeration performance of nepheline nepheline not only reduced agglomeration temperature of ceramic tile but also improved ceramic tile bending strength evidenfiy .

〔2〕加入一定量的石英对霞石烧结性能有显著的影响。〔3〕霞石替代长石不仅降低瓷砖烧成温度，对瓷砖抗折强度也有明显的改善。

The surplus Na2CO3 will later react with nepheline to formalkaline nepheline [(Na2O)0.33NaAlSiO4].The optimal reation condition wasdetermined by the experiments as follows: the ratio of the high-alumina fly ash toNa2CO3 is 1.8:1 by mass,and that the optimal temperature is 850℃ for 90min.The dissolution reaction of nepheline in HCl solution is also thermodynamicallyanalyzed.

对高铝粉煤灰与Na_2CO_3的固相热分解反应的实验研究表明：当Na_2CO_3过量时，过量的Na_2CO_3会与生成的霞石发生反应，生成碱性霞石(Na_2O)_0.33NaAlSiO_4；通过实验确定了Na_2CO_3的最佳用量为：高铝粉煤灰： Na_2CO_3=1.8：1，反应的最佳温度和时间分别为850℃和90min。

The two volcanic materials are similar but are also different ①the partition mode of rare-earth element is similar to that of the basalt.②the increase content of the rare-earth element content in transitional layer shows that it enrichs in this segment due to the volcano events. Moreover, the comparability of the partition mode shows that the volcano-genic materials and the basalt are of the same source.③low Eu anomaly different from the high Eu anomaly of medium-acidic tuff in Meishan section, that show that their formation is different④there are plentiful basalt detritus.⑤there are enrichment of the Ti element.⑥the lower content of siderophile element of Ni and Co, especially in the transitional layer, show that there were not extraterrestrial events and big scale basic or ultrabasic volcano eruption events in this area. These characteristics show that the sedimentary source of Xuanwei Formation and Kayitou Formation is basalt.

1稀土元素配分模式与玄武岩类似；(2)稀土元素含量在异常层的增加反映了火山事件导致了它在该段地层中的富集，而配分模式的相似性反映了火山物质来源与玄武岩具有同源性；(3)低"Eu"异常区别于煤山剖面的中酸性凝灰岩高"Eu"异常模式，说明界线粘土岩成因也不同于煤山剖面的界线粘土；(4)大量的玄武岩岩屑；(5)Ti元素的富集；(6)亲铁元素Ni和Co含量较低，特别是在界线异常层含量降低，表明本区在界线处可能并不存在地外事件和大规模基性、超基性火山喷发事件，这些特征反映本区宣威组和卡以头组物质来源主要为玄武岩。
