| Summary: | Glasses with chemical composition of (70.0)B203-(5.0)TeO2-(25.0-x) Li2C03xNd2O
where x = 0, 0.2, 0.4, 0.6, 0.8 and 1.0 mol% are prepared by melt
quenching technique. By varying the proportion of Li2C03 and Nd2O3, the effect
of this chemical to the lithium boro-tellurite can be investigate in term of physical
properties such as density, molar volume and oxygen packing density (OPD). The
structural properties were measured by using X-ray Diffraction (XRD) technique
and Fourier Tranform Infrared (FTIR) spectroscopy. In this work, generally
density and oxygen packing density are found increase while molar volume is
decrease as the concentration of neodymium oxide is increases. On the other hand,
the amorphous nature was proved by XRD technique and there are presence of
Nd-O, Te-O, B-O and OH functional group of glass in FTIR spectra |
