abstract = {Solid-state sintering at high temperatures is commonly used
to densify solid electrolytes. Yet, optimizing phase purity,
structure, and grain sizes of solid electrolytes is
challenging due to the lack of understanding of relevant
processes during sintering. Here, we use an in situ
environmental scanning electron microscopy (ESEM) to monitor
the sintering behavior of NASICON-type Li1.3Al0.3Ti1.7(PO4)3
(LATP) at low environmental pressures. Our results show that
while no major morphological changes are observed at 10–2
Pa and only coarsening is induced at 10 Pa, environmental
pressures of 300 and 750 Pa lead to the formation of
typically sintered LATP electrolytes. Furthermore, the use
of pressure as an additional parameter in sintering allows
the grain size and shape of electrolyte particles to be
controlled.},
