WebbWe are able to demonstrate unequivocally that the short Te–O bonds present in TeO2 glass become shorter, and stronger, in the high-temperature liquid, something which is typically associated with a reduction in coordination number,19-20 and which is qualitatively consistent with interpretations of Raman scattering spectra.8 This has implications for … WebbSupporting: 1, Mentioning: 16 - The first polar molybdenum oxyfluoride in selenite and tellurite systems, namely, Ba(MoO 2 F) 2 (SeO 3 ) 2 and Ba(MoO 2 F) 2 (TeO 3 ) 2 , was achieved successfully by partial fluorination of MoO 6 octahedra under hydrothermal reactions. Their structures feature a unique staggered grid layer with trans O−Mo−O …
WebbRaman spectra show that addition of Na2O to TeO2 + SeO2 glass may result in cleavage of Te-O-Te and Se-O-Se linkages and formation of TeO3-and SeO 3-terminal groups in the glass system. FTIR spectra show that the units of TeO 4 units decrease and the units of TeO3 / TeO3+1 increase in the tested glass samples.
