An analysis and brief discussion of experimental ionic conductivity s and activation energy EA in the binary rubidium and cesium silicate systems is presented, exemplified on 23 and 30 glasses respect...
The coordination environment of 20-200 ppm Pt in yellowish glasses from the CaO-Al O -SiO 2 3 2(CAS) ternary was studied using X-ray absorption fine structure spectroscopy at the Pt-L edge. IIIedge...
The effect of water (5 H2O 1 OH) on the environment of Co21and Ni21 in albite glass was investigated by electronic absorption spectroscopy. The visible spectra of Co21-doped glasses change only slight...

The coordination environment of Ti in eight Ti-bearing glasses of the Na Si-Na,Ti y4 ;:join (NTS) and in six ATY2 glasses (A20Ti02.2Y02, with A =Na, K, ~r Rb andSi or Ge) was determined using high-re...
In situ, high-temperature Raman spectroscopy of Na,O.9SiO, glasses and melts with and without 2 mol% P,05 has been conducted to 1491 K (near the liquidus temperature). In the temperature range from 29...
