The processing of commercially available hydroxyapatite powder by atmospheric slip casting is discussed. Powders are heat t reated before use in order to increase the solids loading in suspensions. Mixtures are prepared in an attrition mill. Colloidal stability (as a function of pH and deflocculant concentration), casting, drying and sintering behaviour are studied. Strength values obtained from baIlon-ring tests on as slip casted and sintered samples are used to optimize this processing route. The maximum strength measured in this way is 177 ± 25 MPa.
