Production of Ti foams using acicular carbamide as space holder in the case of spacer content between 60%~80% has been investigated. Ti foams having porosities in the range of 50.2%~71.4% have been manufactured. The SEM microstructure shows that the connectivity degree of macrospores grows with higher spacer content, and Ti foams with open-cell structure are formed when the spacer content is beyond 70%. The compressive tests indicate that the mechanical properties of Ti foams decrease with increasing porosity. The resultant yield strength, compressive strength and Young’s modulus vary in the range of 34.4~146.8 MPa, 40.6~193.2 MPa and 0.5~3.3 GPa, respectively. Ti foams with porosity 50.2% and 71.4% may theoretically serve as potential substituted materials for cortical and cancellous bone, respectively.
