Preparation of Thin Cordierite Sheets by Aqueous Tape Casting

Abstract:

Aqueous tape casting process was used to prepare the thin cordierite sheets, the influences of dispersant (PAAS), the rate of plasticizer (PEG),and binder (PVA),content (R) and drying temperature on the tape casting process were investigated, the sintering character of the sheets were studied after drying. It was showed that when the content of PAAS was 1wt%, the slurries were stable uniform and the shear thinning was reversible. The green sheets with the thickness of 177μm showed good flexibility, lubricious surface and compact microstructure when R was 0.7 and the drying temperature was 25°C. A compact α-cordierite sheet was obtained at 1000°Csintering for 2h.
