Nkọwa na Atụmatụ

Nkọwa: WNX na-eji teknụzụ mmepụta akpaaka dị elu ma na-eji ihe eji emepụta ihe dị elu iji mepụta ihe dị eluLanthanum Hydroxide.

Isi Atụmatụ:

Ịdị ọcha dị elu:Lanthanum Hydroxide enweghị ihe ruru unyi sitere na ihe ndị dị n'ụwa dị ụkọ (dịka iron, calcium, sodium), ihe ruru unyi dị n'ime ya dịkwa obere.

Ezi mgbaze:Lanthanum Hydroxide nwere ike ịgbaze ngwa ngwa n'ime mmiri na asịd siri ike.

Nkwekọ: Njikwa ogbe siri ike na mmepụta nkeLanthanum Hydroxide na-eme ka mma kwụsiri ike maka mmepụta nnukwu ụlọ ọrụ mmepụta ihe.

Ihe na-akpali mmepụta kemịkalụ: Lithium hydroxide bụ isi ihe dị mkpa na mmepụta nke ihe na-akpali mmepụta mmanụ petroleum fluid catalytic cracking (FCC). Ọ nwere ike ime ka arụmọrụ na ịdị mma nke mmepụta mmanụ dịkwuo mma, na-emezu ụkpụrụ gburugburu ebe obibi maka mmanụ dị ọcha (dịka Euro V na Euro VI). Enwere ike iji ya dị ka ihe na-akpali akpali maka nhicha ikuku ụgbọala, na-enyere aka ịgbanwe gas ndị na-emerụ ahụ.

Ihe Na-ewepụ Phosphorus nke Ọma: N'ihi ihe ndị dị na kemịkalụ ya, lanthanum hydroxide nwere ike iwepụ phosphate n'ime mmiri nke ọma site na mmiri ozuzo, a na-ejikwa ya nke ọma na ọgwụgwọ mmiri mkpofu na njikwa nke eutrophication n'ọdọ mmiri na ọdọ mmiri. Ọ nwere ike igbochi uto nke algae nke ọma.

Batrị na ihe ndị e ji arụ ọrụ ike: Lithium hydroxide na-arụ ọrụ dị oke mkpa n'ịmepụta batrị nickel-metal hydride (NiMH), nke a na-ejikarị eme ihe n'ụgbọala ngwakọ. Na mgbakwunye, ọ bụ ihe nwere ike ibute ihe ndị dị mkpa na sel mmanụ siri ike (SOFC) na teknụzụ batrị siri ike na-apụta.

Njikọta kemịkalụ: Dịka ihe dị mkpa maka ihe eji emepụta ihe, a na-ejikarị lanthanum hydroxide eme ihe n'ọtụtụ ebe na njikọta nke ihe ndị ọzọ dị na lanthanum, dịka lanthanum oxide, lanthanum fluoride, na nnu lanthanum dị iche iche. Ihe ndị a bụ ntọala maka imepụta iko pụrụ iche, seramiiki ziri ezi, capacitors seramiiki multilayer (MLCC), na ihe ndị na-egbukepụ egbukepụ n'ụwa.
