In acid pulp, the depressing abilities of reagents on diaspore are in the order of hydroxamic acid starch＞dialdehyde starch＞carboxymethyl starch＞cationic starch＞primary starch. In addition, hydroxamic acid starch and carboxymethyl starch can activate kaolinite without influence on the recoveries of pyrophyllite and illite, so the two reagents have great potential and prospect to be the depressant of diaspore and the activator of kaolinite in bauxite reverse flotation.(3) By oximation of the copolymer of acrylamide and methyl acrylate, hydroxamic acid polyacrylamide is synthesized.

Hexachlorocyclophosphazene was prepared using phosphorous pentachloride and ammonium chloride as raw material, hccp was mixed with Montmorillonite which aimed to decrease MMT.'s hydrophilicity. Solid state reserve cell of Mg│reformed MMT.│polymer gel containing water│graphite was assembled, and cell performance was tested. XRD and IR results show: When mass percentage lower than 9.1%, hccp mixed with MMT to form homophase, hccp phase was observed in the mixture when percentage higher than 9.1%, for hccp specific diffraction peak appears in XRD data, and 1220cm-1 which was assigned to P=N double bond 's expand vibration appears in IR data.

合成了六氯环三磷腈，并用六氯环三磷腈与蒙脱石混合对其改性，期望能减小蒙脱石的吸水性能；组装电池Mg |改性蒙脱石|含水凝胶|石墨片，并测试电池的性能。X射线粉末衍射数据和红外光谱数据表明：蒙脱石容纳六氯环三磷腈的质量分数在4.8%-9.1%之间，可与蒙脱石形成单一物相，但混合质量分数大于9.1%时，改性蒙脱石出现六氯环三磷腈的特征衍射峰，和1220 cm-1的六氯环三磷腈P=N双键的特征伸缩振动峰，证明为蒙脱石与六氯环三磷腈的两相混合。

Firstly, the specific surface area of nano-coated particle is much larger than that of ordinary wollastonite, and the edges formed in comminuting is passivated, which made the slippy crystal surface coarsened. At the same time, the color of nano-coated particle became whiter, which fit for light ware. Secondly, if the coated wollastonite hasn't been modified by coupling agent, the toughness of PP/ wollastonite composite couldn't be improved.

在硅灰石表面包覆上纳米级SiO2小颗粒对硅灰石的应用特性有重要影响：①纳米包覆粒子填料的比表面积比普通硅灰石大，纳米级SiO2小颗粒钝化了由于机械力粉碎造成的硅灰石的棱角，使其平滑的晶体解理面变得粗糙，同时硅灰石粉体白度增大，可应用于浅色制品。

The result shows that a great mass of kaolinite and boehmite in Zhungar coal are turned ioto mullite. There is no boehmite and less kaolinite found in Shenhua coal, so there won't be too much mullite formed.
