High porosity titanium foams are used to replace bone structures with low elastic modulus due to their ability to avoid the phenomenon of stress shielding. Producing foams with porosity levels above 70 % in volume using space holders is challenging because the component can collapse or lose shape during processing. In this study, commercially pure Ti powder was mixed with 50, 70, and 80 vol% potassium chloride (KCl) as space holder, cold-compacted, and sintered in a plasma-assisted reactor to obtain high porosity foams. Plasma-assisted technique was used to remove KCl using heat in the sintering reactor. The porous amount of the foams was measured using Archimedes principle and studied through X-ray microcomputed tomography, and the elastic modulus of the foams was measured using ultrasonic wave transmission. The present study showed that the space holder method and plasma sintering can produce CP-Ti foams with predictable porous architecture, reduced shrinkage, and increased porosity than conventional sintering. © 2024 Elsevier B.V.CAPES-COOPBRASS, (88887.652053/2021-00)
