The transport of potassium and rubidium ions through glasses containing the respective alkali ion as mobile species has been investigated by means of bombardment induced ion transport (BIIT) and impedance spectroscopy (IS). The conductivities as well as the activation energies derived from the two approaches are in agreement lending further support to the recently developed BIIT approach.
The anodic process during electro-thermal poling of one bioactive and three bioabsorbable glasses was investigated by means of impedance spectroscopy and time-of-flight secondary ion mass spectrometry (ToF-SIMS). The bioactive glass with the nominal composition 46.4% SiO 2 , 25.2% Na 2 O, 25.2% CaO, 3.2% P 2 O 5 (46S4) and the three bioabsorbable glasses of the CaX...
