G\u00f6zeneklilik genellikle ~90 aras\u0131nda olup, hatta \u2019e kadar \u00e7\u0131kabilmektedir. Y\u00fcksek bir \u00f6zg\u00fcl y\u00fczey alan\u0131na sahiptir ve g\u00f6zenek da\u011f\u0131l\u0131m\u0131 nispeten d\u00fczg\u00fcnd\u00fcr; se\u00e7ilen g\u00f6zenek boyutuna sahip g\u00f6zenekli seramik \u00fcr\u00fcnler, 0,05~600 \u03bcum g\u00f6zenek boyutu aral\u0131\u011f\u0131nda \u00fcretilebilir. Is\u0131 direnci, g\u00f6zenekli metal malzemeler ve g\u00f6zenekli polimer malzemelerinkinden daha iyidir. Y\u00fcksek s\u0131cakl\u0131\u011fa dayan\u0131kl\u0131 malzemelerden \u00fcretilen seramik g\u00f6zenekli malzemeler, erimi\u015f \u00e7eli\u011fi veya y\u00fcksek s\u0131cakl\u0131ktaki gaz\u0131 filtrelemek i\u00e7in kullan\u0131l\u0131r.<\/p>\n
