abstract = {The reactivity of the MgO powder employed in the
formulation of Mg–K phosphate ceramics can be modulated
through the calcination temperature of MgCO3 source
material, which has a direct impact on production costs.
Upon annealing, MgO undergoes sintering, and in order to
optimize the design of products for applications, it is of
primary importance to disclose the link between the
sintering temperature, reaction mechanisms, microstructure
and performance in this class of ceramics. Small angle
neutron scattering was used to measure the specific surface
area of pores in samples aged 30 days produced with 5
different MgO powders, and to follow the evolution of pore
size distribution during the setting reaction, in a
time-resolved experiment. Quantification of amorphous and
crystalline fraction up to 28 days was accomplished in
synchronous with flexural strength tests. Results indicate
that mechanical properties improve thanks to the progressive
buildup of a pervasive network of tabular crystals filling
the entire volume. Increasing the sintering temperature
above 1500 °C yields a more compact ceramic, with less, but
larger, pores, containing more crystalline fraction and less
amorphous. This is consistent with the recently proposed
mechanisms describing the ceramic setting reaction. The
analysis of the fractured surface suggests that strength
might be effectively improved modifying the density and
orientation of crystals in the ceramic volume, a way for
engineering new tailor-made ceramics.},
