Seramik k\u00f6p\u00fck filtreler, erimi\u015f metal filtrasyonunda yayg\u0131n olarak kullan\u0131lmaktad\u0131r. Poli\u00fcretan k\u00f6p\u00fckten \u00fcretilir, kurutulur ve sinterlenir. G\u00f6zeneklilik oran\u0131 80% \u2013 90% kadar y\u00fcksektir. Seramik k\u00f6p\u00fck filtre, a\u011f yap\u0131s\u0131na sahiptir ve belirli bir mukavemete sahiptir. Erimi\u015f metal y\u00fczeyindeki bas\u0131n\u00e7 fark\u0131na ve metal ak\u0131\u015f\u0131n\u0131n etkisine dayanabilir, ancak k\u0131r\u0131lgan ve hassast\u0131r. Malzemenin hassas yap\u0131s\u0131, homojen kalitesi ve geni\u015f y\u00fczey alan\u0131 sayesinde filtrasyon etkisi \u00e7ok iyidir.<\/p>\n
