Dab tsi yog tungsten trioxide siv rau?
Tungsten trioxideyog siv rau ntau lub hom phiaj hauv kev lag luam, xws li tungsten thiab tungstate tsim uas tau siv ua xas ray thaws cov ntaub ua pov thawj. Nws yog siv los ua cov xim ceramic. Nanowires ntawm tungsten (vi) oxide muaj peev xwm ntawm kev nqus tau cov feem pua siab dua ntawm cov hluav taws xob tshav ntuj txij li thaum nws nqus xiav lub teeb.
Hauv lub neej txhua hnub, tungsten trioxide yog nquag siv rau hauv kev tsim khoom tungstates rau xoo hluav taws xob phosphors, rau cov ntaub thaiv hluav taws xob thiab cov roj txheem. Vim tias nws cov nplua nuj xim daj, WO3 kuj yog siv los ua cov xim hauv Ceramics thiab cov xim av.
