Abstract: The presence of the tricalcium phosphate phase in hydroxyapatite foam ceramics after annealing at 1200°C during 3 h leads to a certain decrease in porosity from 45% to 27 – 38%, to an increase in the degree of resorption and to a significant decrease in the static strength from 3 – 7 to 0,2 – 0,4 MPa.
Keywords: hydroxyapatite foam ceramics, tricalcium phosphate, polyurethane foam, polyvinyl alcohol.
