The fabrication of Au-base metallic glass spheres and microballoons used for ICF targets is described. Alloys of composition Au55Pb22.5Sb22.5 were used because of its low melting point and high Z number. Metallic glass microspheres have a high degree of sphericity and surface smoothness and deform homogeneously and isotropically under the high strain rates involved in an ICF implosion. (AIP)
