Porous Ti with controlled pore structure was fabricated by thermal decomposition and sintering process using TiH 2 powders and Polymethylmethacrylates (PMMA) beads as pore forming agent. The beads sizes of 8 and 50 µm were used as a template for fabricating the porous Ti. The TiH 2 powder compacts with 20 and 70 vol% PMMA were prepared by uniaxial pressing and sintered for 2 h at 1100 • C. TGA analysis revealed that the PMMA and TiH 2 were thermally decomposed at about 400 • C forming pores and at about 600 • C into metallic Ti phase. The porosity increased with increase in the amount of PMMA addition. Also, the microstructure observation showed that the pore size and shape were strongly dependent on the PMMA shapes.
