Hoʻohana i ka Cerium Nitrate
1. Hoʻohana ʻia ka Cerium nitrate i ka hana ʻana i nā catalysts ternary, nā uhi kukui kinoea, nā electrodes tungsten molybdenum, nā mea hoʻohui paʻa paʻa, nā ʻāpana ceramic, nā lāʻau lapaʻau, nā reagents kemika a me nā ʻoihana ʻē aʻe.
2. Hiki ke hoʻohana ʻia ka Cerium nitrate e like me ka catalyst no ka phosphate ester hydrolysis, ka malu kukui mahu, ke aniani optical, etc.
3. Hiki ke hoʻohana ʻia ka Cerium nitrate ma ke ʻano he mea hoʻohui no nā ipukukui mahu a me ka catalyst no ka ʻoihana petrochemical. ʻO ia ka mea maka no ka hana ʻana i nā paʻakai cerium. Hoʻohana ʻia ka kemika analytical ma ke ʻano he reagent analytical a ma ka ʻoihana lāʻau lapaʻau.
4. Cerium nitrate Hiki ke hoʻohana ʻia e like me nā reagents analytical a me nā catalysts.
5. Hoʻohana ʻia ka Cerium nitrate i loko o ka ipukukui kaʻa, ke aniani optical, ka ikehu atomic, ka paipu uila a me nā ʻoihana ʻē aʻe.
6. Hoʻohana ʻia ka Cerium nitrate i nā ʻoihana e like me nā huahana tungsten molybdenum (cerium tungsten electrodes, lanthanum tungsten electrodes), ternary catalysts, steam lamp additives, hard alloy refractory metals, etc.

Nānā:Hiki iā mākou ke hāʻawi i kahi pūʻolo kūikawā a i ʻole huahana index e like me ka koi o nā mea kūʻai aku
ʻO ke ʻano hana o ka cerium nitrate:
ʻO ke ʻano o ka waikawa nitric hydrolyzes i kahi hopena waikawa o ka honua hydroxide waiwai nui i ka cerium, hoʻoheheʻe ʻia me ka waikawa nitric, a ma ke alo o ka oxalic acid a i ʻole hydrogen peroxide, hoʻemi ʻia ka 4 valent cerium i ka 3 valent cerium. Ma hope o ka crystallization a me ka hoʻokaʻawale ʻana, hoʻomākaukau ʻia ka huahana cerium nitrate.
