ʻO ke kumukūʻai metala Selenium kiʻekiʻe 99.999% 99.9999% 5n 6n Selenium, pauka Selenium
| Se Selenium | ||
 | ʻAno kino: he 34 ka helu atomika, ʻo 78.89 ke kaumaha atomika. ʻO 4.81g/cm3 ka nui o ka density, ʻo 217 ℃ ka helu heheʻe, ʻo 684.9 ℃ ka helu paila. He paʻa ka Selenium me ka ʻōlinolino metala hina. | |
| Waiwai kemika: Hiki i ka Selenium ke puhi i ka lewa a hoʻouna i ka lapalapa polū, e hoʻopuka i ʻelua selenium oxide. Hiki iā Iit ke pane pololei me ka metala a i ʻole ka mea ʻole metala, me ka hydrogen a me ka halogen, akā ʻaʻole hiki ke pane me ka waikawa inoxidability. | ||
| Nā kikoʻī | Se-5N (99.999%) | Se-6N (99.9999%) |
| Ka nui o ka haumia | ≤10ppm | ≤1ppm |
| Noi | Hoʻohana nui ʻia ʻo Selenium i ka mea o ke kāʻei toner, nā mea photoelectric, nā kiʻi electrostatic a me nā mea ʻē aʻe o nā mea hana optical. | |
E kākau i kāu leka ma aneʻi a hoʻouna mai iā mākou
