摘　　要：为研究热效应对铁磷酸玻璃结构的影响,对40Fe2O3-60P2O5玻璃样品在600-800℃进行热处理,获得了结晶样品。利用XRD、Raman等研究了玻璃结晶化过程中的结构变化,指认了铁磷酸盐玻璃微结构的振动模式的归属。结果表明,在600℃,铁磷酸盐玻璃析出的结晶相主要为：Fe（PO3）3和Fe4（P2O7）3,在700℃、800℃玻璃析出的结晶相主要为Fe4（P2O7）3。利用SEM观察了玻璃样品的微观形貌,结晶相的微观形貌为片状,保温时间延长,片层厚度增加。In order to study the effect of thermal effects on iron phosphate glass structure,some 40Fe2O3-60P2O5 sglasses have been heated from 600 to 800 ℃. The crystallization samples were collected. The structure transformation for the crystallization process of the studied glasses have been investigated using X-ray diffraction（ XRD）,Raman spectra,The vibration mode of iron phosphate glasses was assigned.The results show that the crystal phase in iron phosphate glasses is Fe（ PO3）3and Fe4（ P2O7）3at 600 ℃and Fe4（ P2O7）3has been obtained when heated at 700 ℃,800 ℃. The microstructure of samples were characterized by Scanning Electronic Microscope（ SEM）. The result show that crystal phase is laminated shape and the slice thickness increase gradually with soaking time extend.
