Daftar Isi:
- The making of ceramic membrane for water filtration from Babel�s kaolin, Sukabumi�s clay, grog (from the waste of broken fireclay bricks) and coal as organic additive has been done. Composition of coal powder varies from 0, 5, 10 to 50% (in percent of mass of clay�s mass). The temperature sintering is 1200° C with rate of sintering 2° C per minute. The process of making sample using dry press molding�s method with cylinder dimension and the pressure is 17,45 Mpa. The examination of physics and mechanics characteristic is burn�s shrink, water absorption, compressive strength and the ability of membrane on reducing the turbidity of water, whereas microstructure analysis and micro�s photo using XRD (X-ray diffractometer) and SEM (Scanning Electron Microscopic). The performance test shows there is a saturation point on 25% composition. The greatest compressive strength ( 9.08 MPa) belongs to membrane with 0% composition and the lowest (0.25) MPa is a membrane with 50% composition. The result from the XRD-test indicates that the major formed-phases are mullite and quartz, and the minor formed-phase is cristobalite high. From the micro�s photo shows that membrane with 45% coal more sintered completely than membrane with 5% coal (in percent of mass of clay�s mass).
