He aha ka Tantalum Oxides a me Tantalum Pentoxides i hoʻohana ʻia no?
Hoʻohana ʻia ʻo Tantalum Oxides ma ke ʻano he kumu kumu no nā substrates lithium tantalate i koi ʻia no nā kānana acoustic wave (SAW) i hoʻohana ʻia ma:
• kelepona paʻa lima,• ma ke ano he precursor no ka carbide,• ma ke 'ano he mea ho'ohui e ho'onui ai i ka hua'ōlelo refractive o ke aniani aniani,• ma ke ʻano he mea hoʻoikaika, etc.,ʻoiai hoʻohana ʻia ka niobium oxide i nā seramika uila, ma ke ʻano he catalyst, a ma ke ʻano he mea hoʻohui i ke aniani, etc.
Ma ke ʻano he kiʻekiʻe reflective index a me ka haʻahaʻa haʻahaʻa absorption mea, ua hoʻohana ʻia ʻo Ta2O5 i ke aniani optical, fiber, a me nā mea hana ʻē aʻe.
Hoʻohana ʻia ʻo Tantalum pentoxide (Ta2O5) i ka hana ʻana i nā kristal hoʻokahi lithium tantalate.Hoʻohana ʻia kēia mau kānana SAW i hana ʻia me ka lithium tantalate i nā polokalamu kelepona paʻa e like me nā smartphones, tablet PCs, ultrabooks, GPS applications and smart meters.
