top layer which were sintered at 1150 °C and 1100 °C, respectively.
The average pore size measured was near 6 μm for the supports sintered
at 1250 °C which is important for a good permeability. In the
case of the deposited microfiltration layers, the APS for anorthite and
zirconia top layers were 2.0 and 0.3 μm, respectively. Also, this obtained
product shows an optimum porosity ratio and a good permeability
(1200 l/h m2) for the membrane applications such as water
filtration.
