Polarising Power And Polarisability Of The Ag+ Ion In Glass: The Basicity Of Silver (I) Oxide

Many properties of oxidic glasses are attributable to the state of polarisation of the oxygen atoms. Polarisation is affected by all the cations in the glass but principally by the Si4+, B3+, etc. cations. The extent of polarisation exerted by a metal ion is influenced by its size and its attraction for the negative charge clouds of the anion. Relevant data which include ionic radii and other closely related parameters are shown, for Ag+ and the alkali metal ions, in this paper.
