Into ethi "lanthanum"

Umhlaba ongaqhelekanga, isifaniso esisetyenziswa rhoqo, kunokuthiwa ziivithamini zoshishino ukuba ioyile ligazi leshishini. Iimetali zomhlaba ezingaqhelekanga liqela leemetali, eziqulathe izinto ezili-17 kwitheyibhile yexesha leekhemikhali, ezifanai-lanthanum, i-cerium, kunye ne-praseodymium, ezisetyenziswa kakhulu kwi-elektroniki, ii-petrochemicals, i-metallurgy kunye nezinye iinkalo. Ezi zinto zidlala indima ebalulekileyo ekuphuculeni ukusebenza kunye nokusebenza kweemveliso kunye neenkqubo ezahlukeneyo.

Izazinzulu zinokufumanisa iindlela ezintsha zokusebenzisa iintsimbi zomhlaba ezinqabileyo rhoqo emva kweminyaka emi-3-5, kwaye into enye kwezintandathu ezisandul’ ukuveliswa ixhomekeke kwiintsimbi zomhlaba ezinqabileyo. Oku kubonisa igalelo elibalulekileyo neliqhubekayo elenziwa ziintsimbi zomhlaba ezinqabileyo kuphuhliso lwetekhnoloji kunye nophuhliso.

I-China inemithombo emininzi yeentsimbi ezinqabileyo, ebekwe kwindawo yokuqala kwihlabathi ngokwemithombo, ubungakanani bemveliso, kunye nomthamo wokuthumela ngaphandle. Oku akubonisi nje kuphela ubuninzi bemithombo yendalo yase-China kodwa kukwabonisa amandla ayo amakhulu ekumbiweni, ekucutshungulweni nasekusasazweni kweentsimbi ezinqabileyo. Kwangaxeshanye, i-China kuphela kwelizwe elinokubonelela zonke iintsimbi ezili-17 ezinqabileyo zomhlaba, ingakumbi iintsimbi eziphakathi nezinzima zomhlaba ezinqabileyo ngezicelo ezibalaseleyo zomkhosi. I-China

isikhundla esiphezulu kule nkalo sitsale ingqalelo enkulu kunye nomona kwamanye amazwe.

I-element "lanthanum" yathiywa ngo-1839 xa indoda yaseSweden egama linguMoisander yafumanisa ukuba umhlaba we-cerium uqulethe ezinye izinto. Yaboleka igama lesiGrike elithetha "ifihliwe" ukubiza i-element ngokuthi "iLanthanum", isigqibo esaphawula inyathelo elibalulekileyo ekuhleleni nasekuqondeni izinto zeekhemikhali.

Ukusetyenziswa kwe-lanthanum kubanzi kakhulu. Umzekelo, kwizixhobo ze-piezoelectric, inceda ukuguqula amandla oomatshini abe ngamandla ombane kwaye ngokuchaseneyo, okwenza kube yinto efunekayo kwi-Iisensors kunye nee-actuators. Kwizinto zokufudumeza, i-lanthanum inegalelo ekuphuculeni ukudluliselwa kobushushu kunye nokuzinza. Kwizinto ze-thermoelectric, yonyusa ukusebenza kakuhle kokuguqula ubushushu bube ngumbane. Kwizinto zokuxhathisa imagnethi, iguqula iipropati zemagnethi, ngelixa kwizixhobo ezikhanyayo (umgubo we-LAN), ivelisa ukukhutshwa kokukhanya okucacileyo nokusebenzayo. I-Lanthanum ikwabalulekile kwizixhobo zokugcina ihydrogen, ivumela ukugcinwa kunye nokukhululwa kwehydrogen ngokufanelekileyo. Kwiglasi ekhanyayo, iphucula isalathisi sokuqaqamba kunye nokucaca. Kwizinto ze-laser, ivumela ukuveliswa kwemisebe ye-laser enamandla nechanekileyo. Ukongeza, i-lanthanum isetyenziswa kwizixhobo ezahlukeneyo ze-alloy ukuphucula amandla azo, ukuqina, kunye nezinye iipropati. I-Lanthanum ikwasetyenziswa ekulungiseleleni iimveliso ezininzi zeekhemikhali ze-organic njenge-catalyst, iququzelela ukusabela kweekhemikhali kunye nokuphucula isivuno semveliso. Ngaphezu koko, i-lanthanum isetyenziswa kwiifilimu zezolimo ze-photocatalytic kwamanye amazwe, ezibonise iziphumo ezithembisayo ekuphuculeni ukukhula kwezityalo kunye nokukhuselwa. Kumazwe angaphandle, izazinzulu zinike indima ye-lanthanum kwizityalo igama lesiteketiso elithi "super calcium", ligxininisa ukubaluleka kwayo kwizicelo zezolimo.
