Structural control is an interesting but less studied subject in titanium foam production using space holder technique. In this paper, an empirical equation was reported for the first time to predict the porosity of pure titanium foams. The empirical equation is P = 0.9Sc + 0.011, where P and Sc represent porosity and spacer content, respectively. Results indicate that porosity is always lower than spacer content by approximately 10%. The porosities obtained from this method are also always lower than 90%. A better prediction was obtained in open-cell pure titanium foams in the author’s work and closed-cell titanium alloys foams in others. It was found that the decreased volume of spacer holes during sintering larger than the volume of micropores in cell-walls is a significant phenomenon for space holder technique.
