ixabiso le-tellurium powder Te 99.99%

Iimpawu:

Isilivere emhlophe, ekhazimlayo, isinyithi esiqinileyo. Inyibilika kwi-asidi ye-sulfuric, i-nitric acid, i-potassium hydroxide kunye nesisombululo se-potassium cyanide. Ayinyibiliki emanzini. Inika ivumba elifana negalikhi ekuphefumleni, inokukhuphaza. Yi-p-type semiconductor kwaye i-conductivity yayo inovakalelo ekukhanyeni ukukhanya.

Iingozi:

(Isinyithi kunye neekhompawundi, njengeTe): Ityhefu ngokuphefumla. Ukunyamezela: 0.1 mg / m3 yomoya.

Usetyenziso:

I-Telluriuminokusetyenziswa kwiinkalo ezahlukeneyo, ngokobunyulu bayo. Inokusetyenziswa njengemathiriyeli ye-infrared detector, imathiriyeli yeseli yelanga, imathiriyeli yokupholisa njalo njalo. Isetyenziswa ikakhulu kwikhondukta ephakathi kwesiqingatha, iseli yamandla elanga, into yokupholisa i-electrothermic, into yokupholisa, i-air-sensitive, i-thermosensitive, i-pressure-sensitive, i-photosensitive, i-piezo-electric crystal kunye ne-nuclear radiation detector, i-infrared detector kunye nezinto ezisisiseko.
