ABSTRACT:
Gold preparations are used for the production of highly porous coatings on metal surfaces by means of sintering. 1 to 10% by weight of a pore former is added to these gold preparations, the pore former comprises a material which suddenly decomposes or evaporates at 700.degree. to 1050.degree. C. and escapes from the layer without leaving a residue. Plastics and dental waxes in powder form are preferably used to this end.
