Abstract
Low dieletric glass is a special glass,it has a lot of advantages,such as low density,low dielectric constant and low dielectric loss,the product can be used in the fields of national defense and sophisticated civil field.ZnO for low dielec-tric glass structure and devitrification behavior has a certain effect.Therefore,this paper according to change the content of ZnO to founding to diferent glasses.Research the structure of glass,crystallization,and phase separation by XRD,IR, SEM.The following is the main results:With the increase of ZnO,the vibration of non bridging oxygen becomes strength-en,lead to glass phase separation.At the same temperature,with the increase of ZnO content,glass devitrification increas-ing easily.With the increase of ZnO content,the density of the glass becomes enlarge.When the content of ZnO is 9%, precipitated phase is Al5(BO3)O6,when the content of ZnO is 12%,precipitated phase is Al2ZnO4.关键词
