摘要：
The influence of process atmosphere during sintering is an aspect of nanopowder processing that has not been widely investigated. Reducing the chemical potential of oxygen promotes the beginning of sintering in nanopowder particles of a model oxide material. The importance of oxygen vacancies is shown by both sintering in low oxygen partial pressures and doping with acceptors (see Figure).
