Titel
Microwave-assisted fabrication of titanium hollow spheres with tailored shell structures for various potential applications
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 degrees C result in individual hollow spheres with permeable shells, while sintering at higher temperatures lead to an interconnected hollow-sphere structure with solid shells.
