Process for the surface-modification of flyash and industrial applications thereof have been described in this invention, which involve the new surface-sensitization, the new surface-activation, and the subsequent Cu or Ag coating of the as-received flyash particles in the conventional electroless bath. These new surface-modification processes offer efficient and cost-effective alternatives for the conventional processes which modify the surface of flyash particles with the costlier Sn-Pd catalyst-system. The flyash processed with the new surface-modification processes is also suitable for more number of industrial applications relative to that processed with the costlier Sn-Pd catalyst- system. The as-received flyash particles, processed via new surface-modification processes, find the industrial applications such as the conductive filler for manufacturing the conducting polymers, paints, adhesives, sealers, and resins used for the EMI shielding of the electronic devices, in the lead-based composites used in the automobile industries, and as a catalyst to purify the industrial waste-water by decomposing longer chains of organic molecules into smaller ones. |
