| Abstract |
Macroporous biphasic calcium phosphate bioceramics, for use as bone substitutes, have
been fabricated by cold isostatic pressing and conventional sintering, using naphthalene particles as
a porogen to produce macropores. The resulting ceramics, composite materials made of
hydroxyapatite and β-tricalcium phosphate containing various macroporosities and microporosities,
have been submitted to compression and three-point bending tests. The mechanical tests performed
on the sintered ceramics tend to validate the modelling approach and its hypothesis, i.e. the material
can be considered as a microporous matrix containing isolated macropores, and the critical flaw is a
macropore. |
