Bi-Si-B-O 系溶胶-凝胶玻璃及其熔融-淬火玻璃的结构对比
The Structure Comparison of Bi-Si-B-O Sol-Gel and Melt-quenching Glass
摘要
Abstract
The glassy powder of the Bi-Si-B-Zn-Al-O system is prepared by sol-gel and melt-quenching methods.The powder is characterized by means of XRD, SEM, EMAX, IR, DSC/TG, and the similari-ties and differences of the microstructure under different preparations are explored roughly.The results show that both of the two have amorphous structure.Compared with melt-quenching one, the glassy pow-der of sol-gel method can be broken easily , and the particle size in the range of 1~10μm is obtained af-ter ball milling, the element of which is relatively close to the designed.The network structures of the two kinds of glassy powder are similar, the [ BiO3 ] triangular, [ SiO4 ] tetrahedron and [ BO4 ] tetrahedron forming the glass′s basic network, but the melt-quenching glassy structure in [ SiO4 ] tetrahedron tends to be like framework, which makes the powder structure more stable, the glass transition temperature slight-ly higher than the sol-gel glass, and both of them are less than 600℃.关键词
