\nUranyum, 1789 y\u0131l\u0131nda Martin Heinrich Klaaproth taraf\u0131ndan ke\u015ffedildi. 1841y\u0131l\u0131nda Eugene-Melchior Peligot taraf\u0131ndan izole edilmi\u015ftir. Radyokatif oldu\u011fu ise 1896 y\u0131l\u0131nda Henri Becquerel taraf\u0131ndan bulunmu\u015ftur.
\nUranyumun cama kat\u0131ld\u0131\u011f\u0131 zaman ilgin\u00e7 sar\u0131-ye\u015fil bir renk verir. Zay\u0131f radyoaktif
\nelementtir. Y\u00fcksek yo\u011funlu\u011fa sahiptir. \u00c7elikten daha yumu\u015fakt\u0131r. Kur\u015fundan %65 daha yo\u011fundur. 3 tane allotropu vard\u0131r.
\n\u00b7 Alfa (ortorombik) 667.7\u00b0C nin \u00fczerinde karal\u0131d\u0131r.
\n\u00b7 Beta (tetragonal) 667.7 C – 774.8\u00b0C aras\u0131nda karal\u0131d\u0131r.
\n\u00b7 Gama (k\u00fcbik) 774.8\u00b0C dan erime noktas\u0131 aras\u0131nda kararl\u0131 (bu s\u0131cakl\u0131kta d\u00f6v\u00fclebilir ve yumu\u015fak formda)
\nUranyum mineralleri , uraninit, autinit, tobernit, koffinittir. Minerallerde bulunan uranyum kimyasal reaksiyonlar sonucunda uranyum okside veya di\u011fer formlar\u0131na d\u00f6n\u00fc\u015ft\u00fcr\u00fcl\u00fcr.Metal olarak uranyum, KUF5 ve UF4 bile\u015fiklerinin elektrolizi ile elde edilir.
\n\u00c7ok saf uranyum ise halojenlerinin termal bozunmas\u0131 ile elde edilir.<\/p>\n","protected":false},"excerpt":{"rendered":"
