D\u00f6k\u00fcm \u00fcr\u00fcnlerinde hidrojen ve ince par\u00e7ac\u0131klar\u0131n bulunmas\u0131 ciddi bir sorundur; zira d\u00f6k\u00fcm \u00e7ubuklar \u00fczerinde i\u015flenen nihai \u00fcr\u00fcnler (s\u00fcrekli \u015fekillendirilmi\u015f \u00e7ubuklar ve teller gibi), zay\u0131f bir tane yap\u0131s\u0131na sahip olur ve bu nedenle mekanik \u00f6zellikleri d\u00fc\u015fer.

Geleneksel olarak, erimi\u015f metal, eriyi\u011fin bekletme f\u0131r\u0131n\u0131nda veya bir potada i\u015flenmesiyle partiler halinde ak\u0131 i\u015flemine tabi tutulur.

Buna ek olarak, partiler halinde ak\u0131 i\u015flemi uyguland\u0131ktan sonra bile, hidrojenin yeniden emilmesi ve metalin sistemde bulunabilecek nemle reaksiyona girerek daha fazla hidrojen \u00fcretmesi nedeniyle, genellikle d\u00f6k\u00fcmde b\u00fcy\u00fck miktarda hidrojen kal\u0131r. Buna ek olarak, erimi\u015f metali refrakter filtrelerden ge\u00e7irme y\u00f6ntemleri, ince par\u00e7ac\u0131kl\u0131 kat\u0131 maddeleri giderme konusunda genel olarak tatmin edici olsa da, erimi\u015f metalin gaz i\u00e7eri\u011fini \u00f6nemli \u00f6l\u00e7\u00fcde azaltma a\u00e7\u0131s\u0131ndan avantajl\u0131 de\u011fildir.<\/p>\n
