Fast Ion Conductor - Examples

Examples

Examples of fast ion conductors include beta-alumina solid electrolyte, beta-lead fluoride, zirconium dioxide, silver iodide.

  • Inorganic materials:
    • Zirconium dioxide doped with calcium oxide and yttrium oxide, which is conductive for O2- ions and is used in oxygen sensors
    • Beta-alumina solid electrolyte used as a membrane in several types of molten salt electrochemical cells
    • Lanthanum(III) fluoride, conductive for F- ions, used in some ion selective electrodes
    • Silver sulfide, conductive for Ag+ ions, used in some ion selective electrodes
    • Silver iodide, conductive at higher temperatures
    • Copper iodide
    • Beta-lead fluoride, exhibits a continuous growth of conductivity on heating. This property was first discovered by M. Faraday
    • Lead(II) chloride, conductive at higher temperatures
    • Rubidium silver iodide, conductive at room temperature
    • Some perovskite ceramics - strontium titanate, strontium stannate - conductive for O2- ions
    • Zr(HPO4)2.nH2O - conductive for H+ ions
    • UO2HPO4.4H2O - conductive for H+ ions
    • Conductive ceramics - e.g. NASICON (Na3Zr2Si2PO12), a sodium super-ionic conductor
  • Organic materials:
    • Gels - polyacrylamides, agar - polymer holds a solution of ion electrolyte
    • A salt dissolved in a polymer - e.g. lithium perchlorate in polyethylene oxide
    • Polyelectrolytes / Ionomers - e.g. Nafion, a H+ conductor

Famous quotes containing the word examples:

    “In the examples that I here bring in of what I have [read], heard, done or said, I have refrained from daring to alter even the smallest and most indifferent circumstances. My conscience falsifies not an iota; for my knowledge I cannot answer.”
    —Michel de Montaigne (1533–1592)

    “Histories are more full of examples of the fidelity of dogs than of friends.”
    —Alexander Pope (1688–1744)

    “No rules exist, and examples are simply life-savers answering the appeals of rules making vain attempts to exist.”
    —André Breton (1896–1966)
