Abstract:
Because of their novel physical and chemical properties when compared with conventional loose sintered porous titanium, titanium foams with large pores and high porosity are attractive in fields of aerospace, biomedicine, new energy automobile and environmental protection. On the basis of the writers research, this paper gives a review on space holders in preparation of titanium foams. First of all, the category of space holders was summarized and classified in accordance with their attributes. Then the most extensive kinds of space holders: carbamide, NH4HCO3 and NaCl, were sieved from analyzing literatures and their speciality, removal process and structure features of obtained titanium foams were emphatically introduced. Finally the future development trends of space holders were pointed out.
