摘要：
Following the mechanism of heterogeneous nucleation, orthosilicate nuclei deposited on surface of fly ash micro-bead, forming a shell with micro and nano-scale structure, just like nano-scale structure on lotus leaf. Optimized coating-reaction condition is discussed. These composite micro-beads can be used for cheaper super-hydrophobic coating.
