mutengo we tellurium powder Te 99.99%

Hunhu:

Sirivha chena, inopenya, simbi yakasimba. Soluble mu sulfuric acid, nitric acid, potassium hydroxide uye potassium cyanide solution. Insoluble mumvura. Inopa kunhuhwirira kwakafanana negariki pakufema, inogona kuburitsa. Iyo p-mhando semiconductor uye conductivity yayo inonzwa kuratidzwa kwechiedza.

Njodzi

(Simbi nemakomponi, seTe): Chepfu nekufemesa. Kushivirira: 0.1 mg / m3 yemhepo.

Applications:

Telluriuminogona kushandiswa munzvimbo dzakasiyana, zvichienderana nekuchena kwayo. Inogona kushandiswa se infrared detector zvinhu, solar cell material, inotonhorera zvinhu uye zvichingodaro. Inonyanya kushandiswa kune komputa semi-conductor, solar energy cell, electrothermic transition element, inotonhorera chinhu, air-sensitive, thermosensitive, pressure-sensitive, photosensitive, piezo-electric crystal uye nuclear radiation detector, infrared detector uye basic material.
