niobium pentoxide hmoov rau optical iav
Product Description
Niobium pentoxide hmoovyog ib qho tseem ceeb chemical raw khoom.Nws kuj yog cov hmoov dub nrog lub siab melting point thiab ruaj khov tshuaj, uas yog tsim los ntawm cov tshuaj tiv thaiv ntawm cov hlau niobium nrog oxygen ntawm qhov kub thiab txias.Niobium pentoxide hmoov muaj cov tshuaj lom neeg ruaj khov, tsis muaj dej, acids thiab cov hauv paus, thiab tsuas yog ua haujlwm nrog hydrogen thiab carbon ntawm qhov kub thiab txias.Niobium pentoxide hmoov yog dav siv hauv electronics, ceramics, optics, chemistry thiab lwm yam kev lag luam.Hauv kev lag luam hluav taws xob, nws yog siv los ua cov khoom siv cathode rau cov phom hluav taws xob, thiab hauv cov khoom siv hluav taws xob, nws yog siv los ua cov khoom siv ntxiv rau cov khoom siv ceramic los txhim kho hardness thiab kub tsis kam ntawm ceramics.Tsis tas li ntawd, niobium pentoxide hmoov kuj tuaj yeem siv rau hauv kev tsim cov khoom siv kho qhov muag thiab cov tshuaj catalysts.
