| Abstract: | The preparation of the paste for Ni electrodes prepared by sintering in atmosphere is presented. The effects of glass and boron content, and sintering technology on the properties of the electrode are discussed. The optimized conditions are as followings: Ni purity 99.5%, particle size -500 meshes, Ni content over wt 65%, glass softening temperature around 450 C, with powered boron as antioxidant, holding time five minutes at 810℃ in atmosphere. Under the above conditions, high adhesion of the electrode to the ceramic substrates and ohmic contact can be acquired. |
| Keywords: | Ni electrode paste sintering in atmosphere ohmic contact semi-conducting ceramics |
