Lintlha tsa motheo
Cerium oxide ke mofuta oa inorganic substance, chemical formula CeO2, light yellow or yellow yellow powder.Density 7.13g/cm3, melting point 2397℃, ha e qhibilihe ka metsing le alkali, e qhibilihang hanyane ka asiti.
Tlas'a mocheso oa 2000 ℃ le khatello ea 15MPa, ceria e ka fumanoa ka ho fokotsa ceria ka hydrogen.Ha mocheso o lokolohile ho 2000 ℃ mme khatello e lokolohile ho 5MPa,
Cerium oxide e bokhubelu bo bosehla, 'me e pinki, ts'ebetso ea eona ke ho etsa lisebelisoa tsa ho bentša, li-catalyst, catalyst carrier (e thusang), ultraviolet absorber, fuel cell electrolyte,Mohatelli oa koloi, lirafshoa tsa elektroniki, joalo-joalo.
Tlhaho:
1. Li-pores ha li thehoe habonolo ha nano-size cerium oxide e kenngoa ka har'a li-ceramics, tse ka ntlafatsang ho teteana le ho qetela ha li-ceramics.
2, nano cerium oxide e na le ts'ebetso e ntle ea catalytic, e loketseng ho sebelisoa lisebelisoa tsa ho roala kapa li-catalysts;
3, nano cerium oxide e ka sebelisoa bakeng sa polasetiki, rabara e khahlanong le ultraviolet, e khahlanong le botsofali, mocheso oa mocheso oa rabara, joalo-joalo Tšebeliso ea mahlahana a khahlanong le botsofali ka liaparo.
Sebaka sa kopo:
1, Catalyst, polishing, additives ea lik'hemik'hale, lirafshoa tsa elektroniki, lirafshoa tsa moralo, monyetla oa UV, lisebelisoa tsa betri.
2. Li-ceramics tse sebetsang hantle;Ho eketsoa ho li-ceramics ho ka fokotsa mocheso oa sintering, ho thibela kholo ea lattice, ho ntlafatsa bongata ba li-ceramics;
3, Alloy coating: eketsa nickel ea zinki, drill ea zinki le alloy ea tšepe ea zinki ho fetola ts'ebetso ea electrocrystallization ea zinki, ho khothalletsa holim'a kristale ho hlahisa mokhoa o khethiloeng, ho roala ha microstructure ho tšoana haholo, ho teteaneng, kahoo ho ntlafatsa ho hanyetsa ha kutu;
4, Polymer: e ka eketsa botsitso ba mocheso oa polymer le ho hanyetsa botsofali.
5, E sebelisoa e le polasetiki, mocheso oa mocheso oa rabara le moemeli oa anti-botsofali
6, Joaloka setlolo sa polasetiki, ntlafatsa coefficient ea lubrication ea polasetiki,
7, Bakeng sa ho bentša.
