二氧化硅

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

通过电镜实验,观察到水合二氧具有微米亚微米纳米三次结构。

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、载体纳米二氧改性剂乙腈与环氧丙烷制备氨钙体系催剂。

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.

水汽氧是水蒸汽为氧气氛，由片表面的原子和水分子反应生成二氧。

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.

用本法测定锌精矿中的二氧与国标法结果吻合。
