Abstract

A solid-state electrolyte CaZr0.98−xIn0.02AlxO3−α (x = 0.002, 0.004, 0.006, and 0.008) was prepared using a solid-state reaction method at the temperatures of 1823 K and 1873 K for 10 h. The structures, micromorphologies, and electrical conductivities of these materials were investigated. The results show that CaZr0.98−xIn0.02AlxO3−α has a pure CaZrO3 perovskite phase structure. The electrical conductivities are approximately 1.86 × 10−8–7.13 × 10−6 S/cm at 1073–1273 K, and they significantly increase with increasing temperature under the same atmospheric conditions and gradually increase with increasing water vapor or oxygen partial pressure. This high-temperature proton conductor material would be used as hydrogen sensors of molten metals.
