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 Oxide.

Isi Atụmatụ:

Ịdị ọcha dị elu:Lanthanum Oxide 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 Oxide nwere ike ịgbaze ngwa ngwa n'ime mmiri na asịd siri ike.

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

Iko na seramiiki anya: Lanthanum oxide bụ isi ihe eji emepụta iko na eriri anya nke ọma, na-eme ka ihe ngosi na-agbanwe agbanwe na ihe ndị na-agbasa nke iko ahụ dịkwuo mma. A na-ejikarị ya eme ihe n'ịmepụta lenzi anya dị elu maka igwefoto na microscopes. N'ọhịa nke seramiiki eletrọnịkị, a na-eji ya dị ka ihe mgbakwunye iji mepụta capacitors seramiiki na seramiiki piezoelectric iji melite ihe onwunwe eletriki na nkwụsi ike okpomọkụ nke ihe ndị ahụ.

Ihe na-akpali akpali: N'ụlọ ọrụ petrochemical, a na-eji lanthanum oxide eme ihe dị ka ihe dị mkpa nke ihe na-akpali akpali nke catalytic cracking (FCC), nke na-enyere aka ịbawanye mmepụta na ịdị mma nke petrol. Ọ nwekwara ike ịbụ ihe na-akpali akpali maka mmeghachi omume kemịkalụ ụfọdụ, dị ka oxidation nke carbon monoxide na mmeghachi omume nke methane oxidation iji mepụta ethane na ethylene.

Ihe eji arụ ọrụ: Lanthanum oxide bụ ihe eji arụ ọrụ maka ịkwadebe lanthanum boride (LaB)₆), nke bụ ihe dị mma maka katode thermoelectronic emission. Lanthanum oxide nwekwara ọrụ dị mkpa n'ọhịa dịka ihe nchekwa hydrogen na sel mmanụ. Dịka ọmụmaatụ, enwere ike iji lanthanum-nickel alloys maka nchekwa hydrogen.
