Freeze tape casting was developed to enable optimization of the microstructures of porous ceramic components for use as solid oxide electrodes in fuel cells.
Porous ceramics tape casting.
Through alignment and grading of pores one can tailor surface areas and diffusion channels for flows of gas and liquid species involved in fuel cell reactions.
Tape casting produces a thin layer of ceramic material by coating a carrier surface thin organic film with a ceramic suspension usually by the doctor blade process.
Conversely the tape casting is one of the main methods not only to produce dense thin ceramics and lately also for obtaining porous ceramic bodies 21.
Tape casting is a well established technique to fabricate ceramic tapes.
