Dispersion behavior of wet chemical synthesized hydroxyapatite

Record type: Conference or Workshop Item (Paper)

The use of hydroxyapatite (HA) as a ceramic material for osteo-implants is restricted because of its low mechanical strength and low toughness. Gelcasting method is used to obtain a high density forming body of HA. In this paper, the wet chemical synthesized HA powder was characterized in order to investigate its dispersing behavior and develop gelcasting slips suitable to produce samples of complex shapes. The maximum value of zeta-potential is 24.6mv at pH8.95. The high loading HA suspension dispersed by the most promising dispersant 1.5wt% ammonium salt of poly(acrylic acid) was formulated at 31 vol%.
