A thick platinum metal layer was deposited on ceramics using electroless- and electro-plating. The ceramics, which consist of ZrO2, Al2O3, SiO2, Na2O, and other oxides, were etched in HF solution, and then immersed in a platinum electroless plating solution containing Pt(NH3)2(NO2)2 and N2H4 as a reducing regent. The mass of the ceramics specimen decreased slightly with the electroless plating time and then increased at a rate depending on temperature, but independent of Pt2+ concentration. A2μm thick platinum layer could be deposited uniformly on ceramics by electroless plating for 14.4ks at 323K. Electroplating of platinum in Pt(NH3)2(NO2)2 solution after electroless plating caused the formation of a platinum layer as think as several tens of microns, and many cracks were formed on the platinum layer after a long period of electroplating.
