PREPARATION OF AU-PASTE BY LIQUID-PHASE REACTION

Preparation of Au-paste by sol-gel-like reactions from the liquid phase was investigated. The Au-paste thus obtained was a well dispersed colloidal gold. The films sintered from the paste were good metallic conductors. These films showed good resistivity despite the presence of included metal oxides such as titania or zirconia in the matrix. The resistivity of the films thus obtained is about 3.0 x 10(-7) OMEGA m, which is not so different from that of pure gold (2.35 x 10(-8) OMEGA m).
