The Electric Conductivity of β-Spodumene and β-Spodumene-SiO2 Solid Solutions

β-spodumene (Li2O⋅Al2O3⋅4SiO2) is isostructral with tetragonal keatite (SiO2) Each Li+ ion locates within zeolite-like channels in β-spodumene structure. On assumption that the Li+ ion in channel will be able to move easily in higher temperature, we prepared the sintering bodies composed of β-spodum...

Summary:β-spodumene (Li2O⋅Al2O3⋅4SiO2) is isostructral with tetragonal keatite (SiO2) Each Li+ ion locates within zeolite-like channels in β-spodumene structure. On assumption that the Li+ ion in channel will be able to move easily in higher temperature, we prepared the sintering bodies composed of β-spodumene and β-spodumene-SiO2 solid solutions and measured the electric conductivity of these in varioust emperatures. As the result, plots of logarithm of the electric conductivity versus the reciprocal absolute temperature were straight lines. The electric conductivity values of β-spodumene were 2.8×10-9Ω-1cm-1 at 100°C and 1.1×10-2Ωcm-1 at 800°C.
