Preliminary Study of Utilizing Coconut Husk Waste as Pore Forming Agent for Clay Based Porous Ceramic

Abstract

This research aims to evaluate the suitability of coconut husk as a pore-forming agent (PFA) for porous ceramic products and to study the effects of coconut husk weight percentage and sintering temperature on porous ceramic physical and mechanical properties. Porous ceramic was produced by the sacrificial fugitive method. The physical properties were determined using water absorption test, apparent porosity, bulk density, linear shrinkage, and crystalline phase. The mechanical properties were determined using compressive strength. The results revealed that increase in the weight percentage of coconut husk (CH) in the porous ceramic decrease the compressive strength and increase the porosity. The highest strength of porous ceramic incorporated with coconut husk is 10 wt.% CH at 950°C sintering temperature and the lowest strength is 30 wt.% CH at 850°C sintering temperature. The well-balanced composition and sintering properties were obtained on the porous ceramic incorporated with 10 wt.% CH and 900°C sintering temperature
