Ibicuruzwa bya rare earth bigira uruhare runini mu iterambere no mu ikoreshwa rya catalysts eshatu, zikaba ari ibintu by'ingenzi mu buryo bwo kugenzura imyuka ihumanya ikirere mu modoka. Izi catalysts zagenewe kugabanya imyuka mibi ituruka muri moteri zitwika imbere, cyane cyane iza azote oxyde, monoxide de carbone, na hydrocarbones. Gushyira ibintu bya rare earth muri catalysts eshatu byazamuye cyane imikorere yabyo n'ubushobozi bwabyo, bituma biba ngombwa cyane mu nganda zikora imodoka.
Ibicuruzwa bya Rare Earth ni itsinda ry'ibintu bya shimi bigaragaza imiterere yihariye ya elegitoroniki, optique, na magnetism. Ibintu bya rare earth nka cerium, lanthanum, na neodymium (Cerium ammonium nitrate, Cerium oxide, cerium nitrate, cerium carbonate, na lanthanum nitrate) ni bimwe mu bintu bya rare earth bikoreshwa cyane mu gukamura. Ibi bintu bizwiho ubushobozi bwo koroshya ibikorwa bitandukanye bya shimi kandi bikoreshwa cyane nk'ibikangura mu nganda. Urugero, oxide ya Cerium ni igice cy'ingenzi mu gukora ibikoresho bishyigikira catalyst, bitanga ubushobozi bwinshi bwo kubika ogisijeni no guteza imbere ihinduka ry'imyanda yangiza mu bintu bidatera ingaruka mbi. Lanthanum na neodymium nabyo bikoreshwa mu kongera ubushyuhe n'imikorere ya catalyst z'inzira eshatu. Gukoresha ibicuruzwa bya rare earth muri ibi bikatangiza byatumye habaho iterambere rikomeye mu ikoranabuhanga ryo kugenzura imyuka ihumanya, bitanga umusanzu mu kubungabunga ibidukikije bisukuye kandi birambye.
Akamaro k'ibikomoka ku butaka budasanzwe mu byuma bitanga umusaruro mu buryo butatu ni ubushobozi bwabyo bwo kunoza imikorere rusange no kuramba kwa sisitemu za catalyst. Binyuze mu miterere yihariye y'ibintu bidasanzwe byo mu butaka, nko ubuso bwabyo burebure, ubushobozi bwo kubika ogisijeni, no kudahungabana k'ubushyuhe, abakora imodoka bashobora gukora catalyst nziza kandi zitangiza ibidukikije. Ibi ntibifasha gusa kubahiriza amategeko akaze y'ibyuka bihumanya ikirere ahubwo binagabanya ingaruka ku bidukikije ziterwa n'ibyuka bihumanya ikirere. Mu gihe inganda z'imodoka zikomeje gushyira imbere ibidukikije birambye n'inshingano zo kubungabunga ibidukikije, ikoreshwa ry'ibikomoka ku butaka budasanzwe mu byuma bitanga umusaruro mu buryo butatu rizakomeza kuba ingenzi mu ikoranabuhanga ryo kugenzura imyuka ihumanya ikirere.
Mu gusoza, ikoreshwa ry'ibikomoka ku butaka budasanzwe mu byuma bitatu byahinduye uburyo bwo kugenzura imyuka ihumanya ikirere mu rwego rw'imodoka. Imiterere yihariye y'ibintu bidasanzwe byatumye habaho iterambere ry'uburyo bugezweho bwo gukwirakwiza imyuka ihumanya ikirere, bifasha mu gutuma ibidukikije birushaho kuba byiza kandi bifite ubuzima bwiza. Uko ikoranabuhanga ry'imodoka rikomeza kwiyongera, akamaro k'ibikomoka ku butaka budasanzwe mu byuma bitatu kazarushaho kugaragara, bigatuma iterambere rirushaho kwiyongera mu ikoranabuhanga ryo kugenzura imyuka ihumanya ikirere.
