Abstract:Bi₂O₃-B₂O₃-SiO₂-ZnO-Al₂O₃-Ga₂O₃-K₂O glass powder was fabricated by high-temperature melting and water quenching.Changing the content of Ga₂O₃ and K₂O in glass powder,the morphology and structure of glass powder were studied.The morphology and composition of glass powder were studied by XRD,SEM,and XPS.The effect of Ga₂O₃ and K₂O content on the network structure of glass powder was analyzed by FTIR and Raman.The results show that Ga₂O₃ and K₂O are involved in forming the network structure of glass powder.K₂O can promote the transformation of [BO₃] triangle into [BO₄] tetrahedron,and the transformation of [BiO₃] tetrahedron into [BiO₆] octahedron.Ga₂O₃ plays the role of network modifier in the glass powder network,structure and has good co-melting with other oxides in the glass powder.
