| titleOfInvention | Preparation method of silver tin oxide electric contact material |
| abstract | The invention relates to a preparation method of a silver tin oxide electric contact material. According to the method, atomized silver tin powder is processed through internal oxidation and then is mixed with tin oxide powder and additives, and the mixture is manufactured into the silver tin oxide electric contact material with the needed specifications through working procedures such as sintering, pressing, wiredrawing and the like. Compared with a traditional electric contact material, the silver tin oxide electric contact material prepared with the method has the characteristics of a power internal oxidation and power mixing method, the rigidity and the plasticity of the silver tin oxide material are enhanced, it is guaranteed that the material has good forming performance, the distribution pattern of the tin oxide can also be improved, the frequency of the phenomenon that tin oxide gathers can be reduced, the homogeneity of a structure is improved, the temperature rise of the contact material is reduced, and the service life of the contact material can be prolonged easily. |
