| dc.description.abstract | The fabrication of porous ceramic has been done by using the basic material
of ZnO and palm shell ash. The mixture of palm shell ash and the raw material of
ceramic (ZnO, Castable, sand) is in mass percentage. The ingredients are arranged
of 30% sample mass of castable and sand is added to each sample and the packages
of the ZnO and palm shell ash using the ratio of O: 70, 5: 65, 10: 60, 15: 55, 20:
50. Each of the sample mixture is stirred in an adequate water by mixer. After the
stirring is homogeneous, it is poured into the mold of 20 cm of height, 4. 7 cm of outer
diameter and 2.1 cm of inner diameter, then allowed to dry in 12 days. After the
drying process, the samples is heated until 1100 °C and hold in 2 hours as well as
cooled in 12 hours. Then the samples are tested both in physically and mechanically.
From the physical testing is found that pores percentages pf 24,27% - 29,06%,
density of 1,35Kglm3
- 1,26 Kglm3 permeabilities of 88,26 Pa - 147,10 Pa, mass
shrinkages of 12,27 % -18,40%, and burning shrinkages oj0,107% -5,600/4, while the
mechanical testing results in the hardness of 114,6 Pa - 99,2 Pa, pressure strength of
2,31 MPa - 1,69 MPa and impact strength of 0,49 J/cm 3
- 1,06 J/m3 The testing of
samples is also done by XRD diffract-meter and SEM in order to obtain the
dominant chemical composition of Zinc Oxide and tested by gas analyser when used
in vehicle exhausted gas system. The using of the filter give the great. amount of
influences in air polution. The absorption of filter usage give the decreasing of
emission of 66,55%-34, 79% CO; 8,19%-4,61% CO2; 8,63 %-0,00 % HC, -1,52%
- 7,93 % O2and the of50 %- 0 %.Nox | en_US |
