Sustainable production of titanium foams for biomedical applications by Concentrated Solar Energy sintering

Porous titanium foams were successfully sintered using a solar parabolic concentrator, of vertical axis and 2kW power, in argon atmosphere. Green pellets were previously prepared following the space holder powder manufacturing route using NaCl as soluble spacer. Titanium foams were fully sintered at...

Description
Summary:Porous titanium foams were successfully sintered using a solar parabolic concentrator, of vertical axis and 2kW power, in argon atmosphere. Green pellets were previously prepared following the space holder powder manufacturing route using NaCl as soluble spacer. Titanium foams were fully sintered at lower temperature and shorter time than in conventional furnace sintering. Moreover, porosity achieved ranges between 58% and 77%, with dual size range: larger porous ranging from 500 to 1000µm resulting from the NaCl particles; and smaller porous of 1–10µm due to the powder sintering. Both the porosity and the porous size obtained for titanium foams produced by solar sintering fulfil the requirements for load-bearing and scaffold applications in tissue engineering.
