The paper presents the morphology of Au, thin films, obtained by pyrolysis of terpene sulfide (or terpene mercaptide or resinate) on ceramic or metallic substrate. The Au films were characterized from morphology point of view using Scanning Electron Microscopy (SEM), after thermal treatment (for 2 hours at 200°C and 1/2 hour at 300°C), and after pyrolysis. After thermal treatment, the grain size of the formed film, with irregular shape was in the range of 25-200μm. The composition of the formed film was determined using a X ray spectrometer. It consists mainly on carbon (72.51 wt.%) and gold (18.23 wt.%). After pyrolysis at 800°C, the film have 1-2μm grains imbedded in a continuous sintered phase, and contains 18.23 wt.% Au and 10.44 wt.% C. The distribution of gold and fluxes (Rh, Pd, Bi, Cr, V) on the surface of the gold thin film was also determined. The distribution of gold and fluxes is highly uniform.
