Buna ek olarak, al\u00fcminyum eriyik i\u00e7inde reaktif g\u00f6zenekler bulunacakt\u0131r; bunlar temel olarak iki t\u00fcrd\u00fcr: erimi\u015f al\u00fcminyum ile kal\u0131nt\u0131lar\u0131n etkile\u015fimi sonucu olu\u015fan g\u00f6zenekler ve erimi\u015f al\u00fcminyumun i\u00e7 bile\u015fenleri aras\u0131ndaki etkile\u015fim sonucu olu\u015fan g\u00f6zenekler. D\u00f6k\u00fcm \u00f6ncesindeki erimi\u015f al\u00fcminyumda, kal\u0131nt\u0131 i\u00e7eri\u011fi y\u00fcksekse veya erimi\u015f al\u00fcminyum y\u00fczeyindeki oksit tabakas\u0131n\u0131n bozulmas\u0131 sonucu oksitlenmi\u015f kal\u0131nt\u0131lar olu\u015fmu\u015fsa, hidrojen birikimi g\u00f6zenek olu\u015fumuna yol a\u00e7acakt\u0131r.<\/p>\n
Deneysel g\u00f6zlemler sonucunda, ince g\u00f6zenekli al\u00fcminan\u0131n b\u00fcy\u00fck miktarda hidrojeni adsorbe edebildi\u011fi, d\u00fcz y\u00fczeyli al\u00fcminan\u0131n ise hidrojeni adsorbe etmedi\u011fi g\u00f6r\u00fclm\u00fc\u015ft\u00fcr; bu da al\u00fcminan\u0131n hidrojen adsorpsiyonunun kimyasal adsorpsiyon de\u011fil, fiziksel adsorpsiyon oldu\u011funu g\u00f6stermektedir. \u00d6zg\u00fcl y\u00fczey alan\u0131 geni\u015f, da\u011f\u0131l\u0131m\u0131 az ve y\u00fczey aktivitesi geli\u015fmi\u015f inkl\u00fczyonlar ne kadar fazla olursa, o kadar fazla hidrojen adsorbe edilir. Aksine, inkl\u00fczyonlar\u0131n boyutu daha b\u00fcy\u00fck ve i\u00e7eri\u011fi y\u00fcksek olsa da, adsorbe edilen hidrojen miktar\u0131 mutlaka fazla olmayabilir.<\/p>\n
Bu nedenle, al\u00fcminyumda g\u00f6zenek olu\u015fumunu etkileyen en \u00f6nemli fakt\u00f6r, kal\u0131nt\u0131lard\u0131r.
