“…Using the values found in Ref. 25 we find the value 9.7ϫ10 Ϫ15 s for the Li containing material, and from Ref. 29 the value 4.8ϫ10 Ϫ14 s is deduced for the corresponding Na compound.…”

“…This is in contrast to the experimental situation, where it is found that the crystal contracts with increasing Li content, at least up to a concentration of 0.56 Li ions per unit cell, where the contraction is 0.4%. 25 The charge distribution in real space naturally bears similarity to that of the pure WO 3 material, except for a small peak around the lithium site. Much more illuminating information about the additional electron is found in Fig.…”

Microwave Preparation of Oxide Bronzes

“…The structure (23,24) consists of regular or distorted WO octahedra, sharing common corners. The electron transport in cubic tungsten bronzes is attributed to the existence of an indirect overlap of tungsten t g orbitals with the oxygen p L orbitals (4) in the W}O}W chains.…”

Chemical Analysis of the Alkali Metal Tungsten Bronzes.

“…The work of Dams and Hoste (2) has been adapted by Dahmer (1) and made the basis for a very successful wet chemical method for determining tungsten. This methcd must be applied to compounds which contain lithium, because the volatility of lithium oxide is low and decomposition of lithium compounds is difficult under most circumstances (7,11).…”
