Large-scale fabrication of silicon carbide hollow spheres
Abstract
The synthesis of SiC hollow spheres is reported. The shell of the spheres is formed through a solid–gas reaction rather than traditional chemical methods. The sphere size can be modulated from the microscale to the nanoscale, and the shell thickness can be finely tuned by adjusting the experimental parameters. This technique presents a new paradigm in the preparation of hollow spheres. Based on this technique, other carbide hollow spheres could also be synthesized.
