intengo ye-tellurium powder Te 99.99%

Izici:

Isiliva elimhlophe, elikhazimulayo, insimbi eqinile.Incibilika ku-sulfuric acid, i-nitric acid, i-potassium hydroxide nesisombululo se-potassium cyanide.Ayincibiliki emanzini.Inikeza iphunga elifana nelikagalikhi ekuphefumuleni, kungaba yi-depilatory.Kuyi-semiconductor yohlobo lwe-p futhi ukuqhutshwa kwayo kuzwela ekuchayekeni ekukhanyeni.

Izingozi:

(Metal and compounds, as Te): Ubuthi ngokuhogela.Ukubekezelela: 0.1 mg/m3 womoya.

Izicelo:

I-Telluriumingasetshenziswa emikhakheni ehlukene, ngokuya ngobumsulwa bayo.Ingasetshenziswa njengezinto zomtshina we-infrared, i-solar cell material, izinto zokupholisa nokunye.Isetshenziswa kakhulu i-semi-conductor ehlanganisiwe, iseli lamandla elanga, i-electrothermic transition element, into epholile, ezwela umoya, i-thermosensitive, i-pressure-sensitive, i-photosensitive, i-piezo-electric crystal kanye nokutholwa kwemisebe ye-nuclear, umtshina we-infrared nezinto eziyisisekelo.
