High Purity Selenium 99.999% 99.9999% 5n 6n Selenium Hlau Nqe Selenium Hmoov
Selenium yog siv nyob rau hauv kev lag luam xws li electronics, iav, metallurgy, tshuaj, kev kho mob, kev ua liaj ua teb, thiab lwm yam, nrog ntau dua selenium noj nyob rau hauv lub iav manufacturing, electronics, tshuaj, thiab metallurgy industries, thiab tsawg dua nyob rau hauv lwm yam lag luam. Nrog rau qhov tshwm sim ntawm kev hloov pauv selenium hauv cov khoom siv hluav taws xob thiab roj teeb, kev noj selenium hauv thaj chaw no yuav poob qis, thaum selenium hauv kev lag luam iav tsis yog lwm txoj hauv kev, yog li kev thov yuav nce ntxiv.
Selenium thiab nws cov tebchaw feem ntau yog siv los ua catalysts, vulcanising agents thiab antioxidants. Selenium raws li lub catalyst muaj qhov zoo ntawm cov tshuaj tiv thaiv me me, tus nqi qis, tsis tshua muaj kuab paug ib puag ncig, thiab yooj yim tom qab kev kho mob, xws li mono selenium yog cov catalyst hauv kev npaj ntawm mono sulfur hauv cov tshuaj tiv thaiv sulphite. Selenium feem ntau yog siv los ua vulcanising tus neeg sawv cev hauv kev tsim cov roj hmab los txhim kho kev puas tsuaj ntawm cov roj hmab.
Selenium muaj photosensitive thiab semiconductor zog, feem ntau siv nyob rau hauv electronics kev lag luam los tsim photocells, photoreceptors, laser li, infrared controllers, phototubes, photoresistors, optical instruments, photometers, rectifiers thiab hais txog. Kev thov selenium hauv kev lag luam hluav taws xob suav txog li 30% ntawm tag nrho cov kev thov. High purity selenium (99.99%) thiab selenium alloys yog lub ntsiab lub teeb absorbing xov xwm nyob rau hauv lub tshuab luam ntawv thiab yog siv nyob rau hauv lub photoreceptors ntawm daim ntawv dawb photocopiers thiab laser printers. Ib qho tseem ceeb ntawm grey selenium yog tias nws muaj cov khoom siv hluav taws xob zoo ib yam thiab tuaj yeem siv rau hauv xov tooj cua yoj nrhiav thiab kho. Selenium rectifiers yog tus cwj pwm los ntawm kev thauj khoom tsis kam, kub tsis kam thiab hluav taws xob zoo.
