Ulwazi olusisiseko:
1.Ifomula yemolekyuli: Se
2.Ubunzima bemolekyuli: 78.96
3.Ugcino: Gcina kwindawo epholileyo, engena umoya neyomileyo.Khusela ukufuma kunye nokuvezwa.
4.Ukupakisha: Le mveliso kufuneka isetyenziswe kwiinyanga ezintandathu, kwaye nceda ubuyisele iintsalela kwiphakheji ye-vacuum.
Iingcaciso:
● I-Selenium sisiqalelo sekhemikhali esinophawu u-Se kunye nenombolo ye-athomu engu-34 kwaye ifunyenwe ngokungacocekanga kwintsimbi yesulfide.
● Iselenium ineeisotophu ezintandathu zendalo.I-Black Selenium yi-brittle, eqinileyo eqinileyo enyibilika kancinane kwi-CS2.
● Isebenza ngobuchule ekuveliseni iselenium yococeko oluphezulu kunye neyona masuntswana amancinane omlinganiselo weesayizi zeenkozo.

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.

FAQ:
Umbuzo: Ngaba uyinkampani yokurhweba okanye umenzi?
A: Siyifektri.
Umbuzo: Lingakanani ixesha lokuhambisa kwakho?
A: Ngokubanzi yi-5-10 iintsuku ukuba iimpahla zikhoyo.okanye yi-15-20 iintsuku ukuba iimpahla azikho kwisitokhwe, ngokobungakanani.
Umbuzo: Ngaba uyabonelela ngeesampuli?isimahla okanye yongeziweyo ?
A: Ewe, singanikezela ngesampulu yentlawulo yasimahla kodwa ungahlawuli iindleko zothutho.
Q: Ithini imiqathango yakho yentlawulo?
A: Intlawulo<=1000USD, 100% kwangaphambili.Intlawulo>= 1000USD, 30% T / T kwangaphambili, ibhalansi ngaphambi kokuthunyelwa.
