Isicelo:
1. I-Selenium ineempawu ezintle ze-photovoltaic kunye ne-photoconductive, kwaye isetyenziswa kakhulu kwi-electronics, njenge-photocells, iimitha zokukhanya kunye neeseli zelanga.
2. Ukusetyenziswa okwesibini okukhulu kwe-selenium kushishino lweglasi: i-selenium isetyenziselwa ukususa umbala kwiglasi, ukunika umbala obomvu kwiiglasi kunye ne-enamels.
3. Ukusetyenziswa kwemizuzu yesithathu, ukuthatha malunga ne-15% ye-sodium selenite yokutya kwezilwanyana kunye nezongezo zokutya.
4. I-Selenium inokufumana izicelo kwi-photocopying, kwi-toning yeefoto.Ukusetyenziswa kwayo kobugcisa kukuqinisa kunye nokwandisa uluhlu lwetoni yemifanekiso emnyama namhlophe yemifanekiso.
5. Olunye usetyenziso lwe-selenium lukwii-alloys zetsimbi ezifana neepleyiti ezikhokelayo ezisetyenziswa kwiibhetri zokugcina nakwizinto ezihlaziyiweyo ukuguqula i-AC yangoku kwi-DC yangoku.
6. I-Selenium isetyenziselwa ukuphucula ukunyanzeliswa kwe-abrasion kwi-rubber vulcanized.Ezinye iikhompawundi ze-selenium zongezwa kwiishampu ezichasene ne-dandruff.
