Özet

Many kind of bioactive materials including bioglasses, bioglass–ceramics, and

calcium phosphate ceramics, have been developed and some of them are now applied to repair

and reconstruct diseased or damaged bones or tissues. Much attention has recently been

devoted to investigation of these materials since they expand the range of bioresorbability and

mechanical properties of bioceramics. The aim of this study is to explain the manufacturing

process of bioceramics with controlled porosity by a simple method. Al2O3 and ZrO2 were

added to the matrix in order to increase the hardness and strength. Sodium-free bioglass

material is derived from reagent grade chemicals. Wood flour with a grain diameter of 100

μm is used as a filling material. Composites were sintered in a furnace at 850°C for 3h. The

samples were characterized from a microstructural point of view, in order to evaluate the pore

morphology, dimension and degree of interconnectivity.
