Tantalum Oxides thiab Tantalum Pentoxides siv rau dab tsi?
Tantalum Oxides yog siv los ua ib qho khoom siv rau lithium tantalate substrates uas yuav tsum tau siv rau cov lim dej saum npoo av (SAW) siv hauv:
• xov tooj ntawm tes,• raws li ib tug precursor rau carbide,• raws li ib tug additive kom lub refractive index ntawm optical iav,• raws li ib tug catalyst, thiab lwm yam.,thaum niobium oxide yog siv nyob rau hauv hluav taws xob ceramics, raws li ib tug catalyst, thiab raws li ib tug additive rau iav, thiab lwm yam.
Raws li qhov ntsuas qhov ntsuas siab siab thiab cov khoom siv tsis pom lub teeb, Ta2O5 tau siv rau hauv cov iav kho qhov muag, fiber ntau, thiab lwm yam khoom siv.
Tantalum pentoxide (Ta2O5) yog siv los tsim cov lithium tantalate ib leeg muaju. Cov lim dej SAW no ua los ntawm lithium tantalate yog siv hauv cov khoom siv mobile kawg xws li smartphones, ntsiav tshuaj PCs, ultrabooks, GPS daim ntawv thov thiab cov ntsuas ntse.
