Tus nqi rau tellurium hmoov Te 99.99%

Yam ntxwv:

Silvery dawb, lustrous, khoom hlau. Soluble nyob rau hauv sulfuric acid, nitric acid, potassium hydroxide thiab potassium cyanide tov. Insoluble hauv dej. Imparts qej zoo li tsw rau ua pa, tuaj yeem depilatory. Nws yog p-hom semiconductor thiab nws cov conductivity yog rhiab rau lub teeb raug.

Kev phom sij:

(Hlau thiab tebchaw, raws li Te): Toxic los ntawm inhalation. Kev kam rau siab: 0.1 mg / m3 ntawm huab cua.

Daim ntawv thov:

Telluriumtuaj yeem siv rau hauv ntau qhov chaw, raws li nws cov purity. Nws tuaj yeem siv los ua cov khoom siv ntsuas hluav taws xob, cov khoom siv hnub ci, cov khoom cua txias thiab lwm yam. Feem ntau yog siv rau cov khoom siv hluav taws xob semi-conductor, lub hnub ci zog ntawm tes, electrothermic hloov lub caij, cua txias, cua-rhiab, thermosensitive, siab-rhiab, photosensitive, piezo-hluav taws xob siv lead ua thiab nuclear hluav taws xob ntes, infrared detector thiab cov khoom siv yooj yim.
