Structure property correlation in lithium borophosphate glasses.
Eur. Phys. J. E 35(1) , 8, (2012) To investigate the influence of cation mobility variation due to the mixed glass former effect, 0.45Li(2)O-(0.55-x)P(2)O(5)-xB(2)O(3) glasses (0≤x≤0.55) are studied keeping the molar ratio of Li(2)O/(P(2)O(5)+B(2)O(3)) constant. Addition of B(2)O(3) into lith... |

Structural investigations on sodium-lead borophosphate glasses doped with vanadyl ions.
J. Phys. Chem. A 116(14) , 3547-55, (2012) Electron paramagnetic resonance (EPR), optical absorption, and FT-IR spectra of vanadyl ions in the sodium-lead borophosphate (Na(2)O-PbO-B(2)O(3)-P(2)O(5)) (SLBP) glass system have been studied. EPR spectra of all the glass samples exhibit resonance signals ... |

In vitro dissolution behavior of SiO2-MgO-Al2O 3-K2O-B2O3-F glass-ceramic system.
J. Mater. Sci. Mater. Med. 19(9) , 3123-33, (2008) Herein, we report the results of the in vitro dissolution tests, which were carried out by immersing the selected glass-ceramic samples in artificial saliva (AS) for various time periods of up to 42 days. In our experiments, the SiO(2)-MgO-Al(2)O(3)-K(2)O-B(2... |

Effect of B2O3 on the removal of phosphate ions from an aqueous solution in borosilicate glasses.
J. Hazard. Mater. 172(2-3) , 1013-20, (2009) Recently, it was found by the authors of this study that glasses of a special composition have an ability to remove some hazardous ions from waste solutions. In the present study, a SiO(2)-B(2)O(3)-CaO-Na(2)O glass system has been chosen to remove phosphate i... |
