摘要/Abstract

摘要： Ce(SO₄)₂-doped phosphosilicate gel was prepared by mechanical milling. Complex impedance analysis proved that the 15 h-ball-milled sample showed a maximum conductivity of 2.97 S/m at 130 °C, which is about 40% higher than that of the sol-gel-prepared sample with the same compositions. NMR results proved that the ball-milled samples contained more Q¹ structural units helpful to an increase in both proton conduction and chemical durability.
