Zeta potential and rheological properties of silicon suspensions have been measured in this work. The results show that the isoelectric point of silicon particles is at the pH of 1.6. It is also found that silicon particles are suitable for suspending in basic solution, provided that a proper pH value is chosen. Silicon suspension with 46 vol.% particles displays a minimum viscosity at the pH of 9.6. The influence of particle concentration on the rheological properties of aqueous silicon suspensions is investigated under steady and oscillatory shear conditions. Furthermore, gelcasting of high concentrated aqueous silicon suspension is also discussed in this paper. By vacuum pumping, controlling pH values of suspensions, high volume fraction green bodies with uniform structure and certain strength were produced.

The interfacial properties and rheological behavior of the maghemite/water system have been investigated in this work. It has been determined that the real pzc and iep values of maghemite immersed in aqueous solution, containing KNO3 as electrolyte, are very close to 6.6. It has also been shown that
The role of pH, additive concentration, aging time and solids loading in determining the rheological properties of aqueous zirconia suspensions, which contained polyelectrolyte and sucrose molecules, was investigated. It was found that at alkaline pH, the appropriate sucrose addition (4 wt.%) enhanc
