摘要
提出以溶胶凝胶法制备含银Na2O-B2O3-SiO2玻璃的工艺及制备过程,用X射线衍射及红外吸收光谱分析制备过程中结构变化,用光学吸收谱、透射电镜及能谱分析确定银胶体粒子的存在及其分布.结果表明,溶胶凝胶法制备与传统熔融法制备的玻璃有相同的结构,且通过适当的热处理工艺可以获得尺寸有一定分布的银粒子.该方法既可以用于颜色玻璃的制备,其产品也可作为制备其他材料的原料.
A sol-gel process to fabricate Ag-doped Na2O-B2O3-SiO2 glass was presented. The flow sheet for experiment was described. X-ray diffraction and infrared absorption spectra were used to determine the structure and its change during fabrication. The optical absorption spectra and TEM were used to testify the existent of Ag colloid particles. The results show that the glass made by the sol-gel method has the same structure as that made by the molten method, and Ag particles with a distribution of sizes have been obtained after well-controlled heat treatment. This method can be used to produce color glass and its product was also the raw material of other devices.
