| Abstract: |
| 1# nickel of which nickel content is 99.96% was treated by vacuum distillation. Saturated vapor pressures of the impurities were calculated under 773K~2023K. And βof some impurities were calculated under certain temperature. Influence of temperature, vacuum degree and time were studied. This 1# nickel was prepared to 0# nickel under the condition: temperature is 1873K, time is 2.5h, and vacuum degree is between 3Pa and 9Pa. |
