Forthcoming articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

  • Effect of sealed sintering on properties of Al doped ZnO varistor ceramics with high voltage gradient and low residual voltage   Order a copy of this article

    Abstract: Zinc oxide varistor have excellent nonlinear voltmeter characteristics and are the core components of key equipment for overvoltage protection in power systems. This study delves into how sealed sintering affects the electrical properties of Al-doped ZnO varistor ceramics. By comparing two formulas (a traditional one and an optimised low-residual-voltage one with higher Al and BiO content) across different sintering environments (open vs. sealed) and temperatures, significant findings were obtained. Under sealed sintering, the optimised formula achieved a 15% lower residual voltage ratio than the traditional formula. Notably, samples sintered at 1,150 C showed optimal performance: a residual voltage ratio(K) of 1.39, leakage current of 1.38 A, and voltage gradient of 285.5 V/mm. Mechanistically, Al doping reduced grain resistivity and residual voltage, while added Bi, Ni, and Co elements increased the grain-boundary surface state density, suppressing leakage current. These outcomes are highly significant for enhancing the overvoltage protection capabilities of power systems.
