摘要：

H3 - 2x Nb (x) M2 - x (PO4)(3) (M = In, Fe) acid phosphates have been obtained by ion exchange from their lithium forms and X-ray powder diffraction, impedance measurements, and Li-7 and H-1 NMR spectroscopy. The parameters of the hexagonal unit cell of the proton-exchanged forms differ only slightly from those of the initial lithium compounds. According to H-1 NMR data, the proton in the acid phosphates is not hydrated. The conductivity of the acid phosphates at high temperatures depends weakly on their composition and is similar to 1.7 x 10(-7) S cm(-1) at 620 K. The activation energy of conduction is 30-33 kJ/mol (430-770 K).
