【摘要】 通过对基础玻璃网络连结程度不同的三个高铁碱硅酸盐玻璃体系进行了穆斯堡尔研究,证明其中Fe³⁺离子对周围氧离子存在较强的集聚作用。这种作用表现在两个方面,即四面体中的Fe_t³⁺对玻璃网络骨架的内极化和八面体中的Fe₀³⁺对网络骨架的外极化。更多还原

【Abstract】 Three Fe2O₃ containing alkali-silicate glass systems in which the connection of glass uetwork are different each other are studied by means of M（?）ssbauer spectro-scopy. It is observed that Fe3+ ions in the glasses have a stronger coagulation effect in comparison with oxygen ions. There are two manifestations of the effect, i.e., the inter-polarization of Fe_t³⁺ in tetrahedra and the outer-polarization of Fe_o³⁺ in octahedra to the glass hetwork.更多还原
