LanthanumAbu ne na sinadarai tare da alamar lau da atomic lamba 57. Tana da gungun abubuwa 15 da ke cikin tebur na lokaci ƙarƙashin karafa.
An fara gano Lanthanum a cikin 1839 ta Sweden Chemist Carl Gustaf Mosandaf Mosandf Mosandaf Mosandf lokacin da ya ware shi daga Cerium nitrate. Sunanta ya fito ne daga kalmar Helenanci "Lanthanein," Wane ne "ya boye" kamar yadda ake samu a cikin Lanthanum sau da yawa hade da sauran abubuwan a ma'adanai daban-daban.
A cikin tsarkakakken tsari, Lanthanum mai taushi ne, silvery-fararen ƙarfe sosai wanda yake mai aiki sosai kuma cikin sauƙi oxidized a cikin iska. Yana daya daga cikin mafi yawan yawan abubuwan lanthanide amma ya fi komai kyau kamar zinari ko platinum.
An fara samun Lanthan-daga ma'adanai kamar Monzite da Basnäsite, wanda ke ɗauke da haɗuwa na abubuwan duniya mai wuya.
Lanthanum yana da kaddarorin da aka sanannu da yawa waɗanda suke amfani da shi da amfani a aikace-aikace iri-iri. Tana da babban melting matsayi mai narkewa kuma yana iya jure yanayin zafi, wanda ya sa ya dace da ayyukan fim, da hasken Studio, da sauran aikace-aikacen da ke buƙatar kafofin haske. Hakanan ana amfani dashi a cikin bututu na Katako na Katako (CRTs) don Televissions da masu sa ido kan kwamfuta.
Ari ga haka, ana amfani da Lanthanum a fagen catalysis, inda zai iya inganta ayyukan wasu masu kara kuzari da aka yi amfani da su a cikin halayen sunadarai. Hakanan ya sami aikace-aikace wajen samar da baturan abin hawa na wutar lantarki, tabarau na gani, kuma a matsayin ƙari a cikin gilashin da kayan aikin yalwa don inganta ƙarfin su.
Ana amfani da mahaɗan Lanthanum a magani kuma. Carbonate Lanthanum, alal misali, za a iya yin wajabta wajabta wa phosphate a matsayin mai bera phosphate don taimakawa wajen sarrafa matakan phophate a cikin jinin da ake ciki da cutar koda. Yana aiki da ɗaure wa phosphate a cikin narkewar narkewa, yana hana sha sha zuwa cikin jini.
Gabaɗaya, Lanthanum abu ne mai ma'ana tare da kewayon aikace-aikace kamar hasken wuta, lantarki, catalysis, ilimin kayan aiki, da magani. Kayan aikinta na musamman da lokacin hutu suna da mahimmanci a cikin fannoni daban-daban na fasaha.

Lanthanum yana da aikace-aikace da yawa a cikin masana'antu daban-daban saboda na musamman kaddarorinsa:
Haske:Ana amfani da Lanthanum a cikin samar da fitilun jirgin ruwa na Carbon, waɗanda ake amfani da su a cikin ayyukan fim, Haske Waye-Staye, da Sightilds. Waɗannan fitilar suna fitar da haske mai zurfi, tana sa su ta dace da aikace-aikacen da suke buƙatar haske mai yawa.
Lantarki:Ana amfani da Lanthanum a cikin bututu na Katako (CRTs) don Televissions da masu sa ido kan kwamfuta. CRTS suna amfani da katako na lantarki don ƙirƙirar hotuna a allon, kuma Lanthanum yana aiki a cikin Uwadan Gilda na waɗannan na'urorin.
Batura:Ana amfani da Lanthanum a cikin kera nickel-karfe hydridees (NIMH), waɗanda ake amfani da su a cikin motocin lantarki (HEVs). Allos-nickel Alloy suna cikin batirin batutuwa batir, yana ba da gudummawa ga aikin ta da iyawarsa.
Oxpics:Ana amfani da Lanthanum a cikin samar da ruwan tabarau na musamman da tabarau. Zai iya haɓaka ƙayyadaddun kayan shafawa da watsawa na waɗannan kayan, yana yin su da amfani a aikace-aikace kamar ruwan tabarau na kyamara da wando.
Kulawa da kaya:Ana amfani da Lanthanum a matsayin mai kara kuzari a cikin tsarin shaye masu shaye. Yana taimaka wa musayar cuta mai cutarwa, kamar nitrogen oxides (nox), carbon monoxide (HC), cikin abubuwa marasa cutarwa.
Gilashin da Glorics:Ana amfani da Lanthanum oxide azaman ƙari a cikin samar da gilashin da kayan yumbu. Yana ba da kyakkyawan zafi da kuma girgiza tsayayya da kaddarorin, yin samfurori na ƙarshe da ke da ƙarfi ga lalacewa.
Aikace-aikace na magani:Abubuwan da ke cikin Linthanum, kamar su Linhanum Carbonate, ana amfani dasu a magani a matsayin maganin phosphate a cikin maganin marasa lafiya da cutar koda. Waɗannan mahaɗan suna ɗaura ga phosphate a cikin narkewa, hana sha sha zuwa cikin jini.
Metallurgy: Za'a iya ƙara Lanthanum ga wasu allures don inganta ƙarfin su da babban zazzabi. Ana amfani dashi a cikin samar da karafa ta musamman da allura don aikace-aikacen kamar Aerospace da injunan masu aiki.
Waɗannan 'yan misalai ne na aikace-aikacen na Lanthanum. Abubuwan kaddarorin na musamman suna sa shi mahimmanci a cikin masana'antu daban-daban, suna ba da gudummawa ga ci gaba a fasaha, makamashi, da tabarau, da kuma kiwon lafiya.
