Abstract
1232116 Electro-depositing metallic filamentary networks CORNING GLASS WORKS May 28 1968 25391/68 Headings H1A A5 and A4D A metallic filamentary interconnected network is made by forming an electro-conductive coating on part of the external surface of a non-electroconductive porous body, e.g. of glass, ceramic or plastic, having intercommunicating pores of diameter not exceeding 200 angstrom units, preferably applying to the outer surface of the coating a non-electro-conductive coating e.g. of wax, and with the electro-conductive coating as the cathode electro-depositing a metal or alloy on the inner surface of the coating and causing metallic filament growth therefrom throughout at least part of the pores, using D.C. or an asymmetric A.C. potential. Part of the pores of the porous body may be filled with an inert non-electro-conductive material e.g. paraffin wax (in CCl 4 ) to prevent deposition of metal therein. The non-electro-conductive coating e.g. of wax may extend over parts of the surface of the porous body thereby sealing the pores therein, e.g. to produce electric circuit patterns within porous glass. At least part of the porous body may be then removed by etching, e.g. with NaOH for 96% silica porous glass prepared by acid leaching a phase-separated boro-silicate glass or with hydrocarbon solvent for porous plastic, to provide a network 16 which extends outwardly from at least one surface of the porous body 4. The filaments deposited may be of Ni, Cr, Zn, Cu, Sn, Pb, Fe, Au, Ag, Pt, Pd, Rh, Al, Cd, Co, In, Hg, V, Tl, Ga, Ge or alloys thereof, e.g. brass, bronze, Co-Ni, Ag-Cd, Fe-Ni, Ag-Zn, Ag-Pb, Pb-Cu, Cu-Sn, Sn-Ni, Cu-Ag, Cu-Ni, Cu-Zn, Sn-Zn or Sn Cd. For example, porous glass, partially sealed with paraffin wax and with an indium film electrode thereon, was immersed, after treating in air saturated with water vapour to avoid cracking in an aqueous plating solution comprising 150g/lg/l Pb (OH) 2Pb CO 3 , 240g/l HF (50%) and 150 g/l H 3 BO 3 , using a Pb anode, to deposit dendrites of Pb within the pores of the glass for a superconductor. For Fe, Sn or Ag electrode-position in porous glass, aqueous plating solutions containing (a) FeCl 2 and CaCl 2 , (b) SnCl 4 and (c) AgNO 3 may be used. Other uses for the filamentary networks, may be glass-to-metal seals, resistors of metal catalysts.
