Codsiga Cerium Oxide
Cerium Oxide, oo sidoo kale loo yaqaan Ceria, ayaa si ballaaran loogu codsadaa dhalooyinka, ceramics iyo wax soo saarka kicinta. Warshadaha galaaska, waxaa loo arkaa inay tahay wakiilka ugu hufan ee dhalada dhalada si sax ah u iftiiminta indhaha. Waxa kale oo loo isticmaalaa in midabaynta dhalada iyadoo lagu ilaalinayo birta xaaladeeda birta ah. Awoodda muraayadda Cerium-doped-ka ah si ay u xannibto iftiinka ultraviolet ayaa loo adeegsadaa soo saarista alaabada caafimadka ah iyo daaqadaha hawada sare. Waxa kale oo loo isticmaalaa in lagaga hortago polymers-ka inay ku madoobaato iftiinka qoraxda iyo in lagu xakameeyo midab beddelka muraayadda telefishanka. Waxaa lagu dabaqaa qaybaha indhaha si loo hagaajiyo waxqabadka. Nadaafadda sare ee Ceria sidoo kale waxaa loo isticmaalaa fosfooraska iyo dopant to crystal.
Cerium oxide, oo sidoo kale loo yaqaano ceria, waa iskudhis ka kooban canaasiirta cerium iyo ogsijiinta oo leh caanaha kiimikada CeO2. Waa budo caddaan ah oo huruud ah ama caddaan ah, oo deggan xaaladaha caadiga ah. Cerium oxide waxay leedahay codsiyo kala duwan, oo ay ku jiraan:
1. Catalyst: Cerium oxide waxa loo isticmaalaa kataliye ahaan habab badan oo warshadeed, sida warshadaha baabuurta ee beddelayaasha catalytic si loo yareeyo qiiqa qiiqa iyo soo saarista shidaalka synthetic.
2. Walaxda dhalaalaysa: Cerium oxide waxa loo isticmaalaa sidii walax dhalada dhalada ah iyo agabka kaleba. Aad bay wax ku ool u tahay nadiifinta meelaha qallafsan iyo ka saarida xagashada.
3. Shidaalka lagu daro: Waxaa loo isticmaali karaa sidii wax lagu daro shidaalka si kor loogu qaado nadiifinta iyo gubista shidaalka.
4. Warshadaha dhalooyinka: Cerium oxide waxaa loo isticmaalaa warshadaha galaaska si ay u soo saaraan muraayad tayo sare leh sababtoo ah waxay kordhin kartaa index refractive waxayna kor u qaadi kartaa cimriga muraayadda.
5. Wax soo saarka unugyada cadceedda: Cerium oxide waxa loo isticmaalaa dahaadh ka samaysan unugyada cadceedda. Guud ahaan, cerium oxide waxay leedahay codsiyo badan waana qayb muhiim ah oo ka mid ah warshadaha kala duwan sababtoo ah sifooyinka gaarka ah.
6.oo loo isticmaalo sida wakiilka midabaynta dhalada iyo budada dhalada dhalada. Sidoo kale loo isticmaalo sida alaabta ceeriin ee samaynta cerium birta ah. Nadiifinta sareeysa ee Cerium dioxide ayaa aad muhiim ugu ah codsiyada walxaha naadirka ah ee fluorescent
