二氧化硅

1.The hydrated silicon dioxide with three layers structure of micron-submicron-millimicron was observed through TEM.

通过电镜实验,水合二氧化硅具有微米亚微米纳米三次结构。

2.Calcium ammine catalyst was prepared with metal calcium,dehydrated liquid ammonia as raw materials,nano-silica as a carrier and acetonitrile and propylene epoxide as modifiers.

采用金属钙、脱水液氨、载体纳米二氧化硅及改性剂乙腈与环氧丙烷制备氨钙体系催化剂。

3.Thewater vapor oxidation is take the high pure water steam as theoxidizing atmosphere, responds the production silicon dioxide by thesilicon chip surface silicon atom and the hydrone.

水汽氧化是以高纯水蒸汽为氧化气氛，由硅片表面的硅原子和水分子反应生成二氧化硅。

4.When this method is used for the determination of silica in zincous concentrate, the results are coincident with country standard method, but this method is simpler and more rapid.

用本法测定中的二氧化硅与国标法结果吻合。
