Abstrakt: The nature of non-stoichiometry in beta alumina is discussed and mechanisms of non-stoichiometric compensation reviewed. Particular attention is given to the modification of non-stoichiometry, notably demonstrated in investigation of hydrogen beta aluminas where more-nearly-stoichiometric materials have been obtained. We survey the properties of both non-stoichiometric and more-nearly-stoichiometric beta aluminas and provide interpretations of the dependence on stoichiometry of conducting plane composition and structure, lattice constants and ionic conductivity.
