| titleOfInvention | Preparation method based on improved silver nickel tin oxide electrical contact material |
| abstract | The preparation method of the silver nickel tin oxide electrical contact material based on the chemical deposition method of the present invention is as follows: Step 1: Weigh tin dioxide and nickel powder respectively, and mix the weighed tin dioxide and nickel powder into a high-energy ball mill, The nickel-tin oxide composite powder is obtained by ball milling under the protection of inert gas. Step 2: use silver nitrate solution and ammonia water to prepare silver ammonia solution; Step 3: add the nickel tin oxide powder obtained in step 1 to the silver ammonia solution formed in step 2 and mix evenly, use a reducing agent, and combine chemical deposition to prepare A silver-nickel-tin oxide composite powder is produced; Step 4: The silver-nickel-tin oxide composite powder obtained in step 3 is sequentially formed and sintered to obtain a silver-nickel-tin oxide electrical contact material. The silver-nickel tin oxide electrical contact material prepared by adding auxiliary elements in the present invention alleviates the problems of redox reaction between Ni and SnO 2 at high temperature during the use of the existing electrical contact material, and is beneficial to improve the silver-nickel tin oxide electrical contact material excellent arc ablation resistance. |
