THERMAL NEUTRON IRRADIATION EFFECT OF LITHIUM BORATE GLASSES

Doped Zinc Lithium Bismuth Borate Glasses

Zinc lithium bismuth borate glasses containing Er in (25x): Bi2O3:20Li2O:20ZnO: 35B2O3:xEr2O3 (where x=1, 1.5,2 mol %) have been prepared by melt-quenching method. The amorphous nature of the glasses was confirmed by x-ray diffraction studies. Optical absorption and fluorescence spectra were recorded at room temperature for all glass samples. Judd-Ofelt intensity parameters Ωλ (λ=2, 4, 6) are e...

Structural Characterization of fly ash doped lithium borate Glasses

Lithium borate glasses with fixed alkali content of 10 Mole % and different modifiers have been prepared. To compare the role of fly ash as a glass modifier the content of glass modifier PbO, Al2O3 have been kept same to 5 mole %. To investigate the structure FTIR and UV-VIS spectra of prepared samples have been taken. From optical data optical band gap and cutoff wavelength have been calculate...

Synthesis and Characterization of Lithium Borate Glasses Containing Bismuth

A lithium bismuth borate glass system is prepared by the conventional melt quenching technique. The Powder X-Ray diffraction analysis of the prepared samples confirms the amorphous nature of the samples. The density and molar volume studies report the change of structure with the increase of bismuth content. The FTIR analysis of the samples revealed that the network structure of the prepared sa...

Thermal Diffusivity of Ceramics During Neutron Irradiation

Effect of neutron-irradiation on optical properties of SiO2- Na2O-MgO-Al2O3 glasses

Silica based glasses are used as nuclear shielding materials. The effect of radiation on these glasses varies as per the constituents used in these glasses. Glasses of different composition of SiO2-Na2OMgO-Al2O3 were made by melt casting techniques. These glasses were irradiated with neutrons of different fluences. Optical absorption measurements of neutron-irradiated silica based glasses were ...
