Abstract

In this study, the effect of sintering temperature and zero valent iron (ZVI) content on the physical properties of functional ceramic filter(alumina based materials) such as strength and porosity were investigated. The fabrication process of the functional ceramic filter were performed under various sintering temperature ($1150^{\circ}C$, $1250^{\circ}C$) and ZVI content (10, 20, 30, 50%) conditions. With increasing the sintering temperature and ZVI content, strength was increased but porosity was decreased. The physical properties for functional ceramic filter showed that the strength and porosity were obtained under ZVI content (50%) and sintering temperature ($1250^{\circ}C$) of 99.01 MPa and 34.5%, respectively.

본 연구는 알루미나 기반의 기능성 세라믹 필터의 물리적 특성(강도와 기공률)에 대하여 소결온도와 영가철(ZVI) 함량의 영향을 파악하는 것이다. 기능성 세라믹 필터의 제조공정은 다양한 소결온도($1150^{\circ}C$, $1250^{\circ}C$)와 ZVI 함량(10, 20, 30, 50%)조건에서 수행하였다. 소결온도와 ZVI 함량의 증가됨에 따라 기능성 세라믹 필터의 강도는 증가하였지만 기공률은 감소하였다. 기능성 세라믹 필터의 강도와 기공률은 50%의 ZVI 함량과 $1250^{\circ}C$의 조건에서 각각 99.01 MPa과 34.5%로 나타났다.
