Effect of binder on the tape casting process of graphite

Recently, reduction in research costs and less practicing experimental procedure are greatly desired. To obtain this purpose experimental design technique is necessary. In this study, Taghuchi experimental design was used to inves-tigate rheological properties of graphite suspension and green tapes considering 5 variables in 4 levels. These va-riables are graphite content, graphite flake size, binder content, dispersant and plasticizer content. The binder has the greatest effect on green tape properties so in this paper we study effect of binder on properties of slips and tapes. After investigating rheological properties the tapes were characterized by measuring density, tensile strength plus the critical fracture strain.
