polished cordierite ceramic rods making process

  • Production of cordierite ceramic by aqueous tape

    2008-3-3 · Tape-casting process was used to produce cordierite ceramics in an aqueous system with polyvinylalcohol (PVA), and polyethyleneglicol (PEG), as binder and plasticizer, respectively. Before starting to tape-casting studies, optimum amount of sodium tripolyphosphate (STPP, Na 5 P 3 O 10 ) was used by sedimentation method for dispersing the powders.
