Utilizing the cold sintering process for sintering the thermally decomposable lead dioxide 82 Views
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
