He aha ka Tantalum Pentoxide?

ʻO ka Tantalum pentoxide (Ta2O5) he pauka keʻokeʻo ʻole keʻokeʻo, ʻo ka oxide maʻamau o ka tantalum, a me ka huahana hope o ka tantalum e ʻā ana i ka lewa. Hoʻohana nui ʻia ia no ka huki ʻana i ka lithium tantalate hoʻokahi kristal a me ka hana ʻana i nā aniani optical kūikawā me ka refraction kiʻekiʻe a me ka haʻahaʻa haʻahaʻa. Hiki ke hoʻohana ʻia e like me ka catalyst ma ka ʻoihana kemika.

Nā mea maka no ka hana ʻana i ka tantalum metala. Hoʻohana pū ʻia i ka ʻoihana uila. Hoʻohana ʻia ia no ka huki ʻana i ka lithium tantalate hoʻokahi aniani a me ka hana ʻana i ke aniani optical kūikawā me ka refraction kiʻekiʻe a me ka haʻahaʻa haʻahaʻa. Hiki ke hoʻohana ʻia e like me ka catalyst ma ka ʻoihana kemika.

ʻO ke ʻano o ka potassium fluorotantalate: E hoʻomoʻa i ka potassium fluorotantalate a me ka sulfuric acid i 400 ° C, e hoʻohui i ka wai i nā reactants a hiki i ka hoʻolapalapa ʻana, e hoʻoheheʻe piha i ka hopena acidified e hydrolyze, e hana ana i nā wai wai wai, a laila e hoʻokaʻawale, holoi, a maloʻo no ka loaʻa ʻana o ka pentoxide ʻElua huahana tantalum .
2. Metal tantalum oxidation ala: dissolve metala tantalum flakes i loko o ka nitric acid a me ka hydrofluoricʻakika hui 'akika, extract a hoʻomaʻemaʻe, precipitate tantalum hydroxide me ka amonia wai, holoi me ka wai, maloʻo, puhi a wili finely e loaa tantalum pentoxide pau huahana.
Palekana Hoʻopili ʻia i loko o nā ʻōmole plastik polyethylene me nā pāpale pālua ʻelua, ʻo kēlā me kēia ʻōmole he 5kg ke kaumaha. Ma hope o ka hoʻopaʻa paʻa ʻia ʻana, waiho ʻia ka ʻeke plastik polyethylene waho i loko o kahi pahu paʻa, hoʻopiha ʻia me nā ʻōpala pepa e pale aku ai i ka neʻe ʻana, a he 20kg ke kaumaha o kēlā me kēia pahu. E kūʻai ma kahi ea, maloʻo, ʻaʻole i hoʻopaʻa ʻia i ka lewa ākea. Pono e hoʻopaʻa ʻia ka ʻeke. E pale i ka ua a me ka pōʻino i ka wā o ka lawe ʻana. Inā he ahi, hiki ke hoʻohana ʻia ka wai, ke one a me nā mea kinai ahi e kinai i ke ahi. ʻO kaʻawaʻawa a me ka palekana: Hiki i ka lepo ke hoʻonāukiuki i ka membrane mucous o ka'ōpū hanu, a hiki i ka lōʻihi o kaʻikeʻana i ka lepo hiki ke hoʻoulu i ka pneumoconiosis. ʻO 10mg/m3 ka nui o ka ʻae ʻia o ka tantalum oxide. I ka hana ʻana i kahi kaiapuni me ka lepo lepo kiʻekiʻe, pono ia e ʻaʻahu i ka mask gas, e pale i ka hoʻokuʻu ʻana o ka lepo oxide, a me ka mīkini a hoʻopaʻa i nā kaʻina hana ʻoki a me ka hoʻopili.
