Hoʻohana i ka Cerium Oxide
ʻO Cerium Oxide, i kapa ʻia ʻo Ceria, ua hoʻohana nui ʻia i ke aniani, nā seramika a me ka hana catalyst.I loko o ka ʻoihana aniani, ua manaʻo ʻia ʻo ia ka mea ʻoi aku ka maikaʻi o ke aniani polishing agent no ka precision optical polishing.Hoʻohana ʻia ia e decolorize i ke aniani ma ka mālama ʻana i ka hao i kona kūlana ferrous.Hoʻohana ʻia ka hiki o ke aniani Cerium-doped e ālai i ke kukui ultra violet i ka hana ʻana i nā kīʻaha lāʻau lapaʻau a me nā puka makani aerospace.Hoʻohana ʻia e pale i nā polymers mai ka pōʻeleʻele i ka lā a me ka hoʻopaʻa ʻana i ka discoloration o ke aniani kīwī.Hoʻohana ʻia i nā ʻāpana optical e hoʻomaikaʻi i ka hana.Hoʻohana ʻia ʻo Ceria maʻemaʻe kiʻekiʻe i ka phosphors a me ka dopant i ke aniani.
ʻO Cerium oxide, i ʻike ʻia ʻo ceria, he hui i haku ʻia me nā mea cerium a me ka oxygen me ke ʻano kemika CeO2.He ʻulaʻula melemele a keʻokeʻo paha, paʻa ma lalo o nā kūlana maʻamau.Loaʻa i ka Cerium oxide nā ʻano hana like ʻole, me:
1. Catalyst: Hoʻohana ʻia ka Cerium oxide ma ke ʻano he catalyst i nā kaʻina hana ʻoihana, e like me ka ʻoihana kaʻa no nā mea hoʻololi catalytic e hōʻemi i ka hoʻokuʻu ʻana a no ka hana ʻana i nā wahie synthetic.
2. Mea hoʻopololei: Hoʻohanaʻia ka Cerium oxide ma keʻano he polishing agent no ke aniani a me nā mea'ē aʻe.He mea maikaʻi loa ia i ka hoʻomaʻamaʻa ʻana i nā ʻili ʻili a me ka wehe ʻana i nā ʻōpala.
3. Hoʻohui wahie: Hiki ke hoʻohana ʻia ma ke ʻano he wahie hoʻohui e hāpai i ka hoʻomaʻemaʻe a ʻoi aku ka maikaʻi o ka puhi ʻana i ka wahie.
4. ʻOihana aniani: Hoʻohana ʻia ka Cerium oxide i ka ʻoihana aniani e hana i ke aniani kiʻekiʻe no ka mea hiki ke hoʻonui i ka index refractive a hoʻonui i ka lōʻihi o ke aniani.
5. ʻO ka hana ʻana o ka cell solar: Hoʻohana ʻia ka Cerium oxide ma ke ʻano he mea uhi no ka hana ʻana i nā cell solar.Ma keʻano holoʻokoʻa, he nui nā noi o ka cerium oxide a he mea koʻikoʻi ia i nā ʻoihana like ʻole ma muli o kāna mau waiwai kūʻokoʻa.
6.used e like me ke aniani decolorizing agent a me ke aniani polishing pauka.Hoʻohana pū ʻia e like me ka mea maka i ka hana ʻana i ka cerium metala.He mea koʻikoʻi ka hoʻomaʻemaʻe kiʻekiʻe ʻo Cerium dioxide i ka hoʻohana ʻana i nā mea fluorescent honua
