abstract = {Functionally graded material (FGM) in terms of grain size
gradation is fabricated from ZnO with a combination of
modified Spark Plasma Sintering (SPS) graphite tooling,
water sintering enhancements through transient liquid phase
surface transport, and strategic SPS mechanical loading. The
grain size gradation of the ZnO FGM spans from 180 nm grains
to 1.2 micrometers in a fully dense material. This is the
first semiconductor or ceramic to be graded
microstructurally to this extent. Predictions of the
microstructure with a Master Sintering Curve (MSC) approach
were done with a series of isothermal experiments on two
different FGM conditions revealing a slight offset due to a
constrained mechanism. The mechanical properties were tested
with Vickers micro hardness across the sample, showing a
gradient in hardness from 2.6 GPa to 4.2 GPa. In addition,
the thermoelectric properties of the FGM were measured and
show a zT of 2 × 10−5 at 100 °C compared to uniform
small- and large-grained samples of 1 × 10−6. This is an
order of magnitude difference making a new path for
improvements of bulk thermoelectric material.},
