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.
Tape casting is a well established technique to fabricate ceramic tapes.
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 of porous materials tape casting is a standard shaping technique used to produce flat ceramic sheets with a thickness range varying between 10 μm to 1 mm.
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.
