Abstract
Effect of dispersant and binder on rheological properties of Si C whisker slurry was investigated by discussing dispersion and viscosity of Si Cwslurry,and then fixed the preparation parameters of slurry. The results indicated that the appropriate content of dispersant( 2 wt%) can effectively weaken whiskers attraction,reduce whiskers cluster,and improve whiskers dispersion. Meanwhile,binder of 3 wt% was used to prepare appropriate viscosity of slurry. By optimizing process parameters,well dispersed slurry with good stability can be obtained to be suitable for tape casting.
