Fabrication of Titanium Doped Hollow Glass Microspheres for Inertial Confinement Fusion Targets by Dried Gel Method

Abstract:

Titanium doped hollow glass microspheres (HGMs) with atom ratio of Ti to Si (Ti/Si) from 2% to 20% were fabricated by dried gel method. Effects of titanium concentration on elements distribution and properties of gels and HGMs were investigated. Results show that elements in both gels and HGMs distribute uniformly when Ti/Si is no more than 5%. On the contrary, sodium chloride are separated out and acetic acid volatilizes from gels with a higher titanium concentration and the elements distribution becomes nonuniform. Furthermore, loss of sodium and acetate ion results in insufficient blowing and refining during the process of fabricating HGMs, and further leads to the decrease of quality on morphology, geometry and uniformity of spheres.
