Abstract: Glass, as a kind of amorphous material, is widely used. It has been found that some important properties of glass will be efficiently improved by coating technology. The advantages and disadvantages of sol-gel coating technology have been introduced in this paper and the application area and development of sol-gel coating technology have also been reviewed. By researching on preparation and controlling of the oxide coatings such as SiO2, TiO2, ZrO2, HfO2, Al2O3, WO3, V2O5, the author get many kinds of functional coatings with controllable optical performance. The hi-strength SiO2 antireflective coatings, which has good performance of optics and mechanics, were prepared by dip-coating method. The results show that the average transmittance of glass coated in this way has been increased by more than 6% at the wave band of 400nm~800nm. The surface of the coatings was smooth and dense. And the mechanical strength was very well. This kind of AR coatings was very useful in practice.
