摘要：

The　CuAl1-xCrxO2　ceramics　were　synthesized　by　solid-phase　reaction　method.　Phase　structure,　element　valence　state,　electrical　properties　of　CuAl1-xCrxO2　ceramics　were　investigated　by　XRD,　XPS,　impedance　spectroscopy　and　Hall　measurement　et.　al..　The　results　show　that　the　main　phases　of　the　sample　are　CuAlO2　and　Cu2O.　Meanwhile,　a　small　amount　of　Cu2+　exists.　The　electrical　conductivity　of　samples　increases　(x=0-0.02)and　then　decreases　(x=0.02-0.05)　as　the　Cr　content　increasing.　The　influence　factor　includes　the　valence　state　of　Cu　cations　and　carrier　mobility.　©　2016,　Chinese　Ceramic　Society.　All　right　reserved.
