1. Y\u00fcksek termal \u015fok direnci; \u00f6n \u0131s\u0131tma s\u0131ras\u0131nda veya erimi\u015f metalle temas halinde \u00e7atlama veya soyulma g\u00f6r\u00fclmez. Seramik k\u00f6p\u00fck malzeme, filtre haznesindeyken enine bas\u0131n\u00e7 gerilimini en aza indirmek i\u00e7in d\u00fc\u015f\u00fck bir termal genle\u015fme katsay\u0131s\u0131na sahiptir.
\n2. Korozyon direnci: Filtre malzemesi, beklenen uygulama aral\u0131\u011f\u0131 (s\u00fcre, s\u0131cakl\u0131k, ala\u015f\u0131m i\u00e7eri\u011fi) dahilinde \u00f6nemli \u00f6l\u00e7\u00fcde reaksiyona girmez.
\n3. Yeterli e\u011filme ve bas\u0131n\u00e7 dayan\u0131m\u0131.
\n4. \u00dcretim ekonomisi.
\n5. D\u00fc\u015f\u00fck yo\u011funluklu veya hafif olmas\u0131, bu da operat\u00f6r i\u00e7in kullan\u0131\u015fl\u0131d\u0131r.<\/p>\n

Seramik k\u00f6p\u00fck filtre hafiftir ve tercihen yakla\u015f\u0131k 0,25-0,40 g\/cc yo\u011funlu\u011fa sahiptir.<\/p>\n
Seramik k\u00f6p\u00fck, seramikten \u00fcretilen dayan\u0131kl\u0131 bir k\u00f6p\u00fck t\u00fcr\u00fcd\u00fcr. \u00dcretim teknikleri aras\u0131nda, a\u00e7\u0131k h\u00fccreli polimer k\u00f6p\u00fcklerin i\u00e7 k\u0131sm\u0131n\u0131n seramik \u00e7amuru ile emprenye edilmesi ve ard\u0131ndan bir f\u0131r\u0131nda pi\u015firilmesi yer al\u0131r; bu i\u015flem sonucunda geriye yaln\u0131zca seramik malzeme kal\u0131r.
