| Abstract: |
| Arsenic was prepared by DC furnace using carbon as reductant. The material is arsenic trioxide of which purity is 98%. Effects of cover temperature, condenser temperature and the weight of carbon were studied. Arsenic was prepared under the conditions: cover temperature is 550℃~600℃, condenser temperature is 450℃?10℃. The reasons why the purity of arsenic is short of 99% were analyzed. And the suggestions of the next step for improvement were advised. |
