first prepare a sintered sample. measure its porosity and pore-size using BET and SEM respectively and then decide which method is suitable for the obtained porosity and pore-size sample.

I would suggest to start with sphere-model at different diameter to prepare green-parts.

For the directional assessment of your specific controlled 'Binders-system'.

SEM maybe adopted to assess the permeability of your Binders-system,

under various temp. profile by using TGA program, to track your Binder behaviors and the permeability conditions at different profile.

Thereafter, you could setup series of DOE to achieve the desired porosity & pore-size sample.

Good luck. Cheers!

Thanks! I wanted to make sure that the sphere-model is appropriate to do my analysis. Do you have any theoretical suggestions to compare my results with?
