| Abstract: | Technological parameter and performance of nano Ag SnO 2 TiO 2 contact material are introduced. The nano SnO 2 TiO 2 mixture powder is synthesized by using sol gel method and the samples of the contact material are prepared through press forming and step isothermal sintering.The performance of the samples meets the specification of chinese standard with specific conductance of 66.9% IACS, density of 9.63/cm 3 and hardness of 92.3kg/cm 2,which is superior to that of the same kind products. |
