XRD and FTIR analysis heat treated lithium bismo-borate glasses doped with 1.0 mol% copper ferrite Available to Purchase

Glasses of compositions of 20Li₂0 • xBi₂O₃• (79-x)B₂O₃ + (1.0 mol%) CuFe₂O₄, with 0 ≤ x ≤ 40 were prepared by melt-quench technique. To obtain the glass–ceramics the controlled heat treatment were given to the prepared glasses. Two nano crystalline phases, i.e., Li₂B₄O₇ and LiB₃O₅ were observed from X-ray diffraction patterns of the prepared glass– ceramic samples. We investigated the change in coordination number of network formers B₂O₃ and Bi₂O₃ and network modifiers Bi₂O₃, Li₂O and CuFe₂O₄. Crystallites size (lies in range ∼47-50nm) and lattice strain (ε) were calculated for major phases for all prepared samples. FT-IR study revealed the de-polymerization of borate groups that change with heat treatment and Bi₂O₃ content. Deconvolution of IR absorption spectra resolves the overlapped and hidden peaks in IR spectra. Sharp and more intense FTIR peaks confirm the vibrations due to crystallites Li₂B₄O₇ and LiB₃O₅ and change in coordination of network forming borate units.
