Abstract

Single crystals of the alkali metal bronzes Na_0.9Mo₆O₁₇, (Li_0.5Na_0.5)_0.9Mo₆O₁₇, Li_0.9Mo₆O₁₇ and Li_0.33MoO₃ were tested as Na⁺-ion sensors. It is shown that single crystals of Na_0.9Mo₆O₁₇ fabricated into electrodes by direct solid-state contact can perform as Na⁺-selective electrodes at temperatures from ambient to 70°C. These sensors respond rapidly and linearly to changing Na⁺ concentration in the range 0.1-1 M and exhibit good stability versus time and temperature. The (Li_0.5Na_0.5)_0.9Mo₆O₁₇ crystal was insensitive to changing Na⁺ concentration while the Li_0.9Mo₆O₁₇ and Li_0.33MoO₃ showed nonlinear behavior.
