 Utilizing the cold sintering process for sintering the thermally decomposable lead dioxide


Author  محمد عاصي احمد الدجيلي  Views and Downloads  323
Description  This work reports, for the first time, the sintering of the thermally decomposable lead dioxide at a temperature lower than 290 °C. Such low-temperature processing is necessary to avoid the transformation of the conductive lead dioxide to the non-conductive lead oxides via the well-known thermal decomposition processes of lead oxides
