SERAMiK FiLTRE ALTLIGI URETiMiNDE LİÇEDiLMiS KAOLEN KULLANIMI

Bu caltsmada seramik filtre altligi uretiminde kuvars, alumina,Jeldspat ve 0.09 M HN03 ile kartsttrma lie 'i islemine tabi tutulmuskaolen kullarulmtsttr. Kaolen'in HN03 ile lie edilmesiyle katt jazdaMgSiD3, NazSiOJ ve KzSiOJ gibi baglaytci metal silikatlar olusmaktadtr.Kaolen'in kartsttrma lic'i 1000 devldk ile 2.5 saat siirede yaptlmtsttr,daha sonra stvt fazt 100 "C'de kurutularak ayrtlmts ve kattfazfiltre altltgt uretiminde kullantlmtsttr. Altltklartn sekillendirilmesifiltrasyon yontemiyle yaptlmts, daha sonra 105 "C'de kurutulan malzemeler1100 "C'de 24 saat sure ile pisirilmistir. Deney sonuclari, liekaolen katktli uretilen filtre altltklarmtn kuru mukavemetlerinin dahayuksek oldugunu gostermistir. Aynca, iiretilen altliklarin pismis mukavemetlerive su gecirgenligi de dahajazla olmustur.
