Null Isotope Study of Lithium Borogermanate Glasses

Abstract: Alkali borogermanate glasses are topologically complex, in that [BOn] (n = 3, 4)and [GeOn] (n = 4, 5, 6) polyhedra may all coexist. Equilibrium between these structural units has significant influence on physico-chemical properties such as conductivity and corrosion resistance. In previous work on the potassium system we used neutron diffraction and NMR to show that K preferentially associates with borate units to form [BO4] in preference to [GeO5] or [GeO6], giving an increase in average coordination of B from 3 to 3.8 but of Ge from 4 to only 4.3. We wish to repeat the study with the lithium system where we can take advantage of the opposite signs of the scattering lengths of the Li-6 and Li-7 isotopes to produce samples which show null scattering from Li. This simplifies the problem and, by comparison with samples formed with natural Li we can study the Li environment itself.
