摘要/Abstract

摘要： 采用溶胶-凝胶法（Sol-Gel）和熔融-淬火法分别制备了Bi-Si-B-Zn-Al-O系玻璃粉体，运用XRD、SEM、EMAX、IR、DSC/TG等手段对粉体进行了表征，并初步探讨了同体系不同制备方法下两种玻璃粉体的微观结构的异同.结果表明，两种玻璃粉体均呈玻璃态，溶胶-凝胶粉体颗粒较易破碎，球磨12 h后可得到1～10 μm范围的颗粒，其元素含量与实验设计比例较为接近；两种粉体玻璃网络结构相似，主要以［BiO₃］三角体、［SiO₄］四面体、［BO₄］四面体构成基本网络骨架；熔融-淬火玻璃结构中［SiO₄］四面体趋向于架状，使得粉体结构更加稳定，玻璃转化温度略高于溶胶-凝胶玻璃且均小于600℃.

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 similarities 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 powder of solgel method can be broken easily, and the particle size in the range of 1~10 μm is obtained after 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 slightly higher than the sol-gel glass, and both of them are less than 600℃.

Key words: sol-gel, melt-quenching, Bi-Si-B-O glassy powder, glass structure
