Ionic ceramics
WebQuestion: 5. For each statement below, choose the bonding type that best completes each phrase. 1) The crystal structures of ceramics are constrained by bond angles associated with the locations of shared electrons within the material. 2) The coordination number of ceramics are constrained by the relative sizes of the compound's component species. WebSome perovskite ceramics – strontium titanate, strontium stannate – conductive for O 2− ions – conductive for H + ions (hydrogen uranyl phosphate tetrahydrate) – conductive for H + ions Cerium (IV) oxide – conductive for O 2− ions Organic materials [ edit] Many gels, such polyacrylamides, agar, etc. are fast ion conductors [10] [11]
