Lithium borate glasses prepared by melt-quench technique have been studied with a view to ascertain their structural and electrical properties. FTIR analysis of the present samples reveals the absence of boroxol rings, presence of structural units of lithium formed with oxygen and increase in the number of Non-Bridging Oxygens (NBOs) in the glass system. The real and imaginary parts of dielectric constant increase with frequency and temperature arises due to interfacial ionic polarization. The non-exponential Kohlrausch-Williams-Watts (KWW) function has been found to follow by the imaginary part of electric modulus, thereby confirming its applicability. The fitting of data of ac conductivity as per Jonscher's universal power law indicates hoppable ion concentration dependent upon temperature and Li₂O content. The analysis is further supported by the variations of ac-conductivity as well as the activation energy for dc conductivity. A decrease in impedance and increase in the space charge polarization is observed with increasing Li₂O concentration. Further, the electrical behavior of samples has been investigated via an impedance equivalent circuit corresponding to the Nyquist plot.

已经研究了通过熔融淬火技术制备的硼酸锂玻璃，以确定它们的结构和电学性能。本样品的 FTIR 分析表明，玻璃体系中不存在硼醇环，存在与氧形成的锂结构单元，以及非桥接氧 (NBO) 数量的增加。由于界面离子极化，介电常数的实部和虚部随着频率和温度的增加而增加。已发现非指数 Kohlrausch-Williams-Watts (KWW) 函数遵循电模量的虚部，从而证实了其适用性。根据 Jonscher 通用幂律对交流电导率数据的拟合表明可跳跃离子浓度取决于温度和 Li ₂哦内容。交流电导率的变化以及直流电导率的活化能进一步支持了该分析。随着Li ₂ O浓度的增加，观察到阻抗降低和空间电荷极化增加。此外，还通过与奈奎斯特图相对应的阻抗等效电路研究了样品的电气行为。
