Abstract
Expanded polystyrene spheres are spray-coated with a Ti–7Ni-0.5B-binder slurry. The polystyrene core and binder are thermally removed and the resulting Ti-7Ni-0.5B shells are sintered by microwave radiation to produce titanium hollow spheres. Samples sintered at ≤1120 °C result in individual hollow spheres with permeable shells, while sintering at higher temperatures lead to an interconnected hollow-sphere structure with solid shells.
► Titanium hollow spheres with different shell structures are fabricated from titanium powder. ► Microwave sintering allows fast fabrication of titanium hollow spheres due to skin depth effect. ► Sintering temperature is critical in determining the shell structure.
