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 ...
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. ...
