intengo ye-tellurium powder Te 99.99%
Incazelo Yomkhiqizo
1.UKUBUKEZWA KWEZIMALI
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. I-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. |
