Abstract

The dispersion behaviour of mechanochemically synthesized hydroxyapatite was investigated. Electrophoretic mobility measurements evidence that pHi.e.p. = 10.7 and that pH modification has a poor effect on the mobility. Surface charge reverses as anionic polyelectrolytes are added in considerably high amounts (3 wt %). Polyacrylates are effective in stabilizing 10 vol % suspensions while pourable casting slips are obtained at the maximum solid concentration of 21.4 vol %. The mechanical properties of the sintered bodies were tested and resulted significantly improved in the slip cast samples if compared with the cold pressed samples, thus proving the importance of the application of the colloidal approach to the optimization of cold consolidation of fine powders.
