Abstract


Calcium phosphate bioceramics with an interconnective pore structure were produced by foaming of hydroxyapatite and methyl phenyl poly(silsequioxane) melts in the temperature range between 250 degrees C and 310 degrees C. The cellular structure of the resulting porous bodies were controlled by foaming parameters and filler load. A porosity of up to 92% was achieved by decreasing the HA-filler amount and increasing the foaming temperature. Subsequent pyrolysis in air at temperatures of 900 degrees C and 1100 degrees C resulted in macroporous foams composed of HA and HA/beta-TCP, respectively. The porous bodies with tailorable structure and composition are of interest for bone tissue engineering scaffolds and orthopedic implants.
