ABSTRACT

The glass system of composition (AgPO₃)_1-x (Ag₂SO₄)_x [where x = 0, 0.15, 0.20, 0.25 Mol%] was prepared using the conventional melt quenching technique. The molar volume and density were determined to characterise the structure of the glasses obtained. X-ray diffraction was used to confirm the amorphous nature of the glass samples used. The absorbance and transmittance were measured in the spectral range of 200–3000 nm for the prepared glasses by using UV-Vis two-beam spectrophotometer. A new modified equation has been formulated to determine the refractive index of the glasses used. Dispersive power, energy gap, dispersion energy and oscillator energy were measured as well. Also, molar refractivity, molecular polarisability and metallization criterion for the glass samples of different Ag₂SO₄ concentrations were calculated.

摘要

玻璃体系的组成 (AgPO ₃ ) _1-x (Ag ₂ SO ₄ ) _x [其中x= 0, 0.15, 0.20, 0.25 Mol%] 是使用传统的熔体淬火技术制备的。测定摩尔体积和密度以表征所得玻璃的结构。X 射线衍射用于确认所用玻璃样品的无定形性质。使用紫外-可见双光束分光光度计在 200-3000 nm 光谱范围内测量制备的玻璃的吸光度和透射率。已经制定了一个新的修正方程来确定所用玻璃的折射率。还测量了色散功率、能隙、色散能量和振荡器能量。此外，计算了不同Ag ₂ SO ₄浓度的玻璃样品的摩尔折射率、分子极化率和金属化标准。
