karfe cerium

Ceriumshi ne karfen da ba kasafai ke da yawa ba, kuma tare da sinadarin yttrium da aka gano a baya, yana bude kofar gano wasu.kasa kasaabubuwa.

A shekara ta 1803, masanin kimiya na Jamus Klaprott ya gano wani sabon sinadarin oxide a cikin wani jajayen dutse mai nauyi da aka samar a cikin ƙaramin birnin Vastras na Sweden, wanda ya bayyana ocher lokacin da yake konewa. A lokaci guda kuma, masanan kimiyar Sweden Bezilius da Hissinger suma sun sami oxide na sinadari ɗaya a cikin ma'adinan. Har zuwa 1875, mutane sun sami cerium na ƙarfe daga narkakken cerium oxide ta hanyar lantarki.

Cerium karfeyana aiki sosai kuma yana iya ƙonewa don samar da cerium oxide foda. Cerium iron alloy gauraye da sauran abubuwan da ba kasafai ake samun su ba na iya samar da kyawawa masu kyawu a lokacin da ake shafawa a kan abubuwa masu wuya, da kunna abubuwan konewa da ke kewaye da su, kuma abu ne mai mahimmanci a cikin na'urorin kunna wuta kamar fitilun wuta da walƙiya. Hakanan za ta ƙone kanta, tare da kyawawan tartsatsi, ƙara ƙarfe da sauran Lanthanide, kawai don haɓaka tasirin waɗannan tartsatsin. Ramin da aka yi da cerium ko wanda aka yi masa ciki da gishirin cerium na iya ƙara tasirin konewar mai kuma ya zama babban taimako na konewa, wanda zai iya adana mai. Cerium kuma wani abu ne mai kyau na gilashi, wanda zai iya sha ultraviolet da infrared haskoki, kuma ana amfani dashi sosai a gilashin Mota. Ba zai iya hana haskoki na ultraviolet kawai ba, amma kuma rage yawan zafin jiki a cikin mota, ceton wutar lantarki don kwandishan.

Ƙarin aikace-aikace na cerium sun dogara ne akan juyawa tsakanin trivalent cerium da tetravalent cerium, waɗanda ke da ƙayyadaddun kaddarorin a cikin ƙananan ƙarfe na ƙasa. Wannan fasalin yana ba da damar cerium don adanawa da sakin iskar oxygen yadda ya kamata, wanda za'a iya amfani dashi a cikin Soyayyen oxide na man fetur don kunna Redox, don haka samun motsin jagorancin electrons don samar da halin yanzu. Zeolites da aka yi ciki tare da cerium da lanthanum na iya zama masu kara kuzari ga fashewar man fetur yayin aikin tacewa. Yin amfani da cerium oxide da karafa masu daraja a cikin masu juyawa na ternary catalytic na mota na iya canza iskar gas mai cutarwa zuwa nitrogen, carbon dioxide, da ruwa mara gurɓatacce, yadda ya kamata yana hana babban adadin hayakin mota. Saboda ikonsa na sha oxygen, mutane kuma suna binciken yadda ake amfani da nanoparticles cerium oxide a cikin maganin antioxidant. Tsarin Laser mai ƙarfi da Amurka ta ƙera ya ƙunshi cerium, wanda za'a iya amfani dashi don gano makaman halittu ta hanyar sanya ido kan tattarawar Tryptophan, kuma ana iya amfani dashi don gano likita.
