Gold is useful for infrared polarization-insensitive mirrors on silica. However, gold does not adhere to bare silica. The adherence is enhanced by depositing an optically thin glue layer of Ni-P on a silica surface after sensitization of the surface with SnF.sub.2 and activation with PdCl.sub.2 /HCl....http://www.google.es/patents/US5864425?utm_source=gb-gplus-sharePatente US5864425 - Low polarization sensitivity gold mirrors on silica
