    Effect of rate controlled sintering on microstructure and electrical properties of ZnO doped with bismuth and antimony oxides

    Various rate controlled sintering (RCS) schedules were used on isostatically pressed particulate compacts of ZnO with Bi2O3 and Sb2O3 additives. For low additive content, smaller average grain sizes with more rap...
