Structural properties and proton conductivity of the 12-tungstophosphoric acid doped aluminosilicate gels
(Solid State Ionics, 1999)
Preparation of aluminosilicate gels bulk, containing 12-tungstophosphoric acid (WPA) in mesopores, as well as their structural and conduction characteristics are reported. Doped gels are prepared from aluminum-silicon ...
Structure and proton conductivity of 12-tungstophosphoric acid doped silica
(Solid State Ionics, 1997)
Sol-gel syntheses offer a wide range of possibilities for introduction of materials with specific properties (electronic, optic and ion-conductive, etc.) into optically clear matrices. Preparation of silica gel bulk, ...
Microwave X-band permittivity measurements on 12-tungstophosphoric acid hexahydrate
(Solid State Ionics, 1997)
Complex permittivity measurements of 12-tungstophosphoric acid hexahydrate (WPA . 6H(2)O) have been performed in the X-band region at room temperature. Permittivity data were obtained by measuring reflection (S-11) and ...
Dielectric investigation of magnesium salt of 12-tungstophosphoric acid hydrate
(Solid State Ionics, 1999)
Magnesium salt of 12-tungstophosphoric acid (WPA) hydrate MgHPW12O40-14H(2)O has been investigated in the microwave (X-band) and in the lower frequency (5 Hz-500 kHz) region. The specimens were obtained by pressing powder. ...
Heteropolyacids as protonic conductors
(Materials Science Forum, 1996)
Protonic conductors belong to the conductors whose charge carriers are proton and protonic entities: H+, OH-, H2O, [H(H2O)(n)](+). A small group of these compounds have exceptionally high proton conductivity, Heteropolyacids ...
