Cerium oxide, oo sidoo kale loo yaqaan ceria, waa walxo la adeegsan karo oo si ballaaran loo isticmaalo oo leh codsiyo kala duwan oo warshado kala duwan ah. Isku dhafkan, oo ka kooban cerium iyo oksijiin, wuxuu leeyahay sifooyin gaar ah oo qiimo u leh ujeedooyin kala duwan.
Kala soocida cerium oxide:
Cerium oxide waxa loo kala saaraa sidii oksaydh bir ah oo naadir ah, oo ka tirsan curiyayaasha taxanaha lanthanide. Waa jaale khafiif ah iyo budo cad oo leh xasillooni kulayl sare leh iyo sifooyin firfircoon oo aad u fiican. Cerium oxide waxaa badanaa laga helaa laba nooc oo kala duwan: cerium (III) oxide iyo cerium (IV) oxide. Cerium (III) oxide waxa loo isticmaalaa kicin ahaan iyo soo saarista dhalada, halka cerium (IV) oxide loo isticmaalo soo saarista xeryahooda dhalaalaysa iyo kicinta falcelinta kiimikaad ee kala duwan.
Isticmaalka cerium oxide:
Cerium oxide waxay leedahay codsiyo kala duwan oo kala duwan sababtoo ah sifooyinka gaarka ah. Mid ka mid ah isticmaalka ugu badan ee cerium oxide waa soo saarista beddelayaasha gawaadhida. Waxay kaa caawinaysaa in la yareeyo qiiqa waxyeellada leh iyadoo u beddelaysa gaasaska sunta ah walxo aan waxyeello lahayn. Intaa waxaa dheer, cerium oxide waxaa loo isticmaalaa wax soo saarka muraayadda, maadaama ay hagaajin karto sifooyinka indhaha iyo kordhinta caabbinta shucaaca UV. Waxa kale oo loo istcimaalaa sidii walax dhalada dhalada, ceramics, iyo biraha, taasoo bixisa meel siman oo ifaysa.
Intaa waxaa dheer, cerium oxide waxaa loo isticmaalaa soo saarista unugyada shidaalka, halkaas oo ay u shaqeyso sidii elektrolyte si ay u fududayso u beddelka tamarta kiimikada tamarta korontada. Dhinaca daawada, cerium oxide nanoparticles ayaa muujiyay suurtagalnimada isticmaalka codsiyada cilmiga noolaha, sida gudbinta daroogada iyo sawir-qaadista. Intaa waxaa dheer, cerium oxide waxaa loo isticmaalaa soo saarista fosfooraska ee iftiinka fluorescent iyo isku dhafka xeryahooda dabiiciga ah ee kala duwan.
Gebogebadii, cerium oxide waa shay qiimo leh oo leh codsiyo kala duwan oo warshado badan ah. Sifooyinkeeda gaarka ah, oo ay ku jiraan catalytic, optical, iyo sifooyinka korantada, ayaa ka dhigaya qayb lagama maarmaan u ah soo saarista alaabada iyo teknoolojiyadda kala duwan. Maaddaama cilmi-baarista iyo horumarinta nanotechnology-ga iyo sayniska agabku ay sii wadaan horumarinta, isticmaalka suurtagalka ah ee cerium oxide waxay u badan tahay inay ballaariso, taasoo sii muujinaysa muhiimada ay u leedahay warshadaha casriga ah.
