【Abstract】 The controllable nanometer porous glasses based on sodium borosilicate glass are prepared.And the influence of heat-treatment on pore size distribution and pore size of controlled porosity glasses is analyzed by scanning electron microscope(SEM) method and differential thermal analysis(DTA) method.Technical parameters are analyzed and optimized by the orthogonal analysis.In order to obtain porous glass medium whose aperture is 70～100 nm,the optimum system is heat-treated at 690 ℃ for 6 hour and acid leached in 2 M hydrochloric acid for 24 hours.The results establish the foundation to prepare nanometer porous glass whose aperture is large and structure is interconnected.更多还原
