abstract = {High-pressure, high-temperature (HP/HT) syntheses are
essential for modern high-performance materials. Phosphorus
nitride, nitridophosphate, and more generally nitride
syntheses benefit greatly from HP/HT conditions. In this
contribution, we present the first systematic in situ
investigation of a nitridophosphate HP/HT synthesis using
the reaction of zinc nitride Zn$_3$N$_2$ and phosphorus(V)
nitride P$_3$N$_5$ to the nitride semiconductor Zn$_2$PN$_3$
as a case study. At a pressure of 8 GPa and temperatures up
to 1300 °C, the reaction was monitored by energy-dispersive
powder X-ray diffraction (ED-PXRD) in a large-volume press
at beamline P61B at DESY. The experiments investigate the
general behavior of the starting materials under extreme
conditions and give insight into the reaction. During cold
compression and subsequent heating, the starting materials
remain crystalline above their ambient-pressure
decomposition points, until a sufficient minimum temperature
is reached and the reaction starts. The reaction proceeds
via ion diffusion at grain boundaries with an exponential
decay in the reaction rate. Raising the temperature above
the minimum required value quickly completes the reaction
and initiates single-crystal growth. After cooling and
decompression, which did not influence the resulting
product, the recovered sample was analyzed by
energy-dispersive X-ray (EDX) spectroscopy.},
