Porous Ceramics Tape Casting
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.
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. This technique has been usually applied to produce dense substrates for electronic applications but recently there are. Freeze tape casting was developed to enable optimization of the microstructures of porous ceramic components for use as solid oxide electrodes in fuel cells. 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.
