摘要：In the present study, influences of the dispersant concentration and solid loading on the rheological properties of magnesium aluminate spinel suspensions are investigated. Aqueous suspensions of commercial spinel powder were prepared by using a polyelectrolyte dispersing agent up to 5?wt%. The viscosity of suspensions decreases continuously with the increase of dispersant concentration; this enables producing MgAl2O4 suspensions containing 30?vol% solid-loading (60?wt%). Green bodies with a relative density larger than 50% were produced from the suspensions; translucent spinel was obtained after sintering at 1550?°C for 2?h.
