Cerium oxide, nke a makwaara dị ka ceria, bụ ihe dị iche iche na nke a na-ejikarị eme ihe nke nwere ngwa dị iche iche n'ofe ụlọ ọrụ dị iche iche. Ngwakọta a, nke mejupụtara cerium na oxygen, nwere ihe pụrụ iche nke na-eme ka ọ baa uru maka ebumnuche dị iche iche.
Nhazi nke cerium oxide:
A na-ekewa cerium oxide dị ka oxide ụwa na-adịghị ahụkebe, nke sitere na usoro ihe nke lanthanide. Ọ bụ ìhè odo na-acha ọcha ntụ ntụ na elu thermal kwụsie ike na magburu onwe catalytic Njirimara. A na-ahụkarị cerium oxide n'ụdị abụọ dị iche iche: cerium (III) oxide na cerium (IV) oxide. A na-eji cerium (III) oxide mee ihe dị ka ihe na-emepụta ihe na mmepụta iko, ebe a na-eji cerium (IV) oxide na-emepụta ogige ndị na-egbuke egbuke na dị ka ihe na-eme ka mmeghachi omume kemịkal dị iche iche.
A na-eji cerium oxide eme ihe:
Cerium oxide nwere ọtụtụ ngwa ngwa n'ihi njirimara ya pụrụ iche. Otu n'ime ihe a na-ejikarị cerium oxide bụ mmepụta nke ihe ntụgharị catalytic maka ụgbọ ala. Ọ na-enyere aka ibelata ikuku na-emerụ ahụ site n'ịgbanwe gas na-egbu egbu ka ọ bụrụ ihe na-adịghị emerụ ahụ. Tụkwasị na nke ahụ, a na-eji cerium oxide na-emepụta iko, n'ihi na ọ nwere ike imeziwanye ihe ndị na-ahụ anya ma mee ka iguzogide radieshon UV dịkwuo elu. A na-ejikwa ya dị ka ihe na-egbuke egbuke maka iko, ceramik, na ọla, na-enye elu dị nro ma na-egbuke egbuke.
Ọzọkwa, a na-eji cerium oxide na-emepụta mkpụrụ ndụ mmanụ ọkụ, ebe ọ na-arụ ọrụ dị ka electrolyte iji kwado ngbanwe nke ike kemịkal na ike eletrik. N'ihe gbasara ọgwụ, cerium oxide nanoparticles egosila ike iji mee ihe na ngwa biomedical, dị ka nnyefe ọgwụ na onyonyo. Na mgbakwunye, a na-eji cerium oxide na-emepụta phosphor maka ọkụ fluorescent yana na njikọ nke ogige organic dị iche iche.
N'ikpeazụ, cerium oxide bụ ihe bara uru nke nwere ngwa dị iche iche n'ofe ụlọ ọrụ dị iche iche. Ngwongwo ya pụrụ iche, gụnyere catalytic, optical, na eletrịkị, na-eme ka ọ bụrụ akụkụ dị mkpa na mmepụta ngwaahịa na teknụzụ dị iche iche. Ka nyocha na mmepe na nanotechnology na sayensị ihe na-aga n'ihu, enwere ike iji cerium oxide gbasaa, na-egosipụtakwa mkpa ọ dị na ụlọ ọrụ ọgbara ọhụrụ.
