A process has been developed at Georgia Tech to fabricate thin-wall hollow spheres from conventinal oxide powders at room temperatur. The polymer-bonded powder shells are fired in air to sinter the walls, leaving the shells either impervious or porous. Alternatively, the oxide shells can be preferentially reduced to produce thin-wall hollow metal spheres which can be bonded together to produce an ultra light weight closed-cell foam. The processing and properties of this unique class of low density strucures will be discussed.
