| Abstract: | Mechanochemical synthesis or reactive milling (RM) is a well-established high-energy milling process for production of a wide range of nanocomposite powders using oxides, carbonates, sulphates or hydroxides as the starting precursors. It ensures chemical reactions such as oxidation/reduction, decomposition or phase transformation in solid-state conditions during room temperature milling, which otherwise require high temperatures. The silver-zinc oxide nanocomposite powders by reactive milling of silver oxide and zinc powder particles have been produced. The resultant Ag-ZnO nanocomposite powders are further processed to bulk solid pieces by conventional powder metallurgy route as electrical contact materials for switchgear applications. |
