Ntibisanzweni icyuma. Isi idasanzwe ni ijambo rusange kubintu 17 byicyuma mumeza yigihe, harimo ibintu bya lanthanide na scandium na yttrium. Hariho ubwoko 250 bwamabuye y'agaciro adasanzwe muri kamere. Umuntu wa mbere wavumbuye isi idasanzwe ni umuhanga mu bya shimi wo muri Finlande Gadolin. Mu 1794, yatandukanije ubwoko bwa mbere bwibintu bidasanzwe byisi nubutare buremereye busa na asfalt.

Ubushinwa bufite ubutunzi bukize cyane ku isi, bwibanda cyane cyane mu ntara no mu mijyi nka Mongoliya y'imbere, Shandong, Sichuan, Jiangxi, n'ibindi, hamwe n'ubwoko bwa ion adsorption yo mu majyepfo hamwe n'ubutaka budasanzwe bw'ubutaka aribwo bugaragara cyane.

Ubutaka budasanzwe mubutaka budasanzwe bwibanze muburyo bwa karubone zidashonga, fluoride, fosifate, okiside, cyangwa silikate. Ibintu bidakunze kubaho ku isi bigomba guhinduka mubintu bivangwa n'amazi cyangwa acide ya organic organique binyuze mumihindagurikire yimiti itandukanye, hanyuma bigahinduka inzira nko gusesa, gutandukana, kwezwa, kwibanda, cyangwa kubara kugirango habeho ibintu bitandukanye bivanze nubutaka budasanzwe nka chloride ivanze nubutaka, Irashobora gukoreshwa nkibicuruzwa cyangwa ibikoresho fatizo byo gutandukanya ibintu bimwe bidasanzwe byisi. Ubu buryo bwitwa isi idasanzwe yibora kubora, bizwi kandi mbere yo kuvura.
