Isku-mid ah: Lanthanum(III) oksaydh, Lanthana, Lanthanum trioxide

Lambarka CAS:1312-81-8

Qaacidda Molekuleeri:La2O3

Miisaanka Molekule:325.8

Muuqaalka:Budada cad, oo aan ku milmin biyaha laakiin ku milmi karta aashitada. Aad bay u hygroscopic badan tahay, si dhakhso ah ayay u nuugi kartaa qoyaanka iyo kaarboon laba ogsaydh hawada waana in lagu kaydiyaa weel xiran.

Sharaxaadda & Astaamaha

Sharaxaad: WNX waxay isticmaashaa tiknoolajiyad wax soo saar oo otomaatig ah oo horumarsan waxayna isticmaashaa agab ceeriin oo tayo sare leh si ay u soo saarto tayo sare lehLanthanum Oxide.

Astaamaha Muhiimka ah:

Nadiifnimo Sare:Lanthanum Oxide ma jiraan wax wasakh ah oo ka yimaada walxaha dhulka naadirka ah (sida birta, kalsiyum, soodhiyam), wasakhduna way yar tahay.

Milmida Wanaagsan:Lanthanum Oxide si degdeg ah ayuu ugu milmi karaa biyaha iyo asiidhyada xooggan.

Joogto ah: Maareynta dufcadda adag ee wax soo saarkaLanthanum Oxide waxay hubisaa tayada xasilloon ee wax soo saarka baaxadda weyn ee warshadaha.

Muraayadaha indhaha iyo dhoobada: Lanthanum oxide waa agabka ugu muhiimsan ee ceeriin ee lagu sameeyo muraayadaha indhaha iyo fiilooyinka indhaha ee saxda ah, taasoo si weyn u xoojinaysa tusmada iftiinka iyo sifooyinka kala firdhinta ee galaaska. Waxaa si weyn loogu isticmaalaa soo saarista muraayadaha indhaha ee horumarsan ee kamaradaha iyo mikroskoobyada. Dhinaca dhoobada elektaroonigga ah, waxaa loo isticmaalaa sidii wax lagu daro si loo soo saaro kaabayaal dhoobada ah iyo dhoobada piezoelectric si loo hagaajiyo sifooyinka korontada iyo xasilloonida heerkulka agabka.

Kaaliyayaasha: Warshadaha batroolka, oksaydhka lanthanum waxaa loo isticmaalaa qayb muhiim ah oo ka mid ah kaaliyayaasha dilaaca catalytic (FCC), kaas oo gacan ka geysta kordhinta wax soo saarka iyo tayada shidaalka. Waxa kale oo uu u adeegi karaa kicinta falgallada kiimikada ee gaarka ah, sida oksaydhka kaarboon monoksaydh iyo falcelinta oksaydhka methane si loo sameeyo ethane iyo ethylene.

Agabka shaqeynaya: Lanthanum oxide waa walaxda cayriin ee loogu talagalay diyaarinta lanthanum boride (LaB)₆), kaas oo ah walxo aad u fiican oo katoos ah oo ku shaqeeya thermoelectronic emission. Lanthanum oxide sidoo kale waxay leedahay codsiyo muhiim ah oo ku saabsan meelaha sida agabka kaydinta haydarojiin iyo unugyada shidaalka. Tusaale ahaan, birta lanthanum-nickel waxaa loo isticmaali karaa kaydinta haydarojiin.
