Prodn. of bone-derived ceramic bodies comprises mineralising roughly preshaped pieces of spongy bone by removing all organic components, sintering the mineralised bone pieces to form ceramic bodies, and ball-milling the ceramic bodies to remove mechanically unstable regions and produce geometrically irregular bodies with rounded corners and edges. The ball mill is made of alumina and contains alumina balls. Milling may be effected in the presence of water, an aq. salt soln. or an organic solvent. |
