二氧化矽
1.Translucent SiO2 sols are prepared from TEOS using NH3?H2O as catalyzer, polyelectrolyte/SiO2 composite films are fabricated via electrostatic self-assembly multilayer method, and SiO2 thin films are formed by heat-treating the polyelectrolyte/SiO2 composite films to eliminate the polyelectrolyte and other components in composite films.
2.The principle and the main parameters of the dry etching for silicon dioxide are introduced.
3.The influence of nano-silica on the properties and microstructure of corundum castable is studied.
4.This is because nano-silica can accelerate the sintering process and promote the densification of corundum castble.
5.A simple route for the synthesis of unique 1D nanostructures, including brush-like gallium nitride nanostructure, oriented amorphous silicon nanowires and In@SiO2 nanocables, was developed on the basis of VLS and SLS mechanisms.
6.The lithographic and etching process for a membrane creates a mesh of metal wires with silicon dioxide filling the space between them.
7.In@SiO2 nanocables were discovered accidentally as we researched in InP nanowires growth.
8.HF-based solution is widely used for cleaning and wet etching SiO2 in pre-diffusion clean process.
9.Analysis of K and Na in nepheline were curried out with higher precision and repeatability by means of adding fluohydric acid during sample melting to remove SiO2 ,adjusting the ratio of K and Na in the solution to reduce the mutual interference of the two elements, and adding cesium chloride to eliminate ionization interference.
