Tungsten Trioxide siv rau dab tsi?
Tungsten Trioxideyog siv rau ntau lub hom phiaj hauv kev lag luam, xws li tungsten thiab tungstate manufacturing uas yog siv los ua X-ray cov ntxaij vab tshaus thiab rau hluav taws pov thawj fabrics.Nws yog siv los ua cov xim ceramic.Nanowires ntawm Tungsten (VI) oxide muaj peev xwm nqus tau qhov feem pua ntawm cov hluav taws xob ntau dua vim nws nqus xiav lub teeb.
Nyob rau hauv lub neej txhua hnub, tungsten Trioxide yog nquag siv nyob rau hauv kev tsim tungstates rau x-ray screen phosphors, rau fireproofing fabrics thiab nyob rau hauv gas sensors.Vim nws cov xim daj nplua nuj, WO3 kuj tseem siv los ua cov xim hauv ceramics thiab xim.
