Mechanical, Microstructural and Mineralogical Analyses of Porous Clay Pots Elaborated with Rice Husks

Abstract

This paper deals with the elaboration of porous ceramic pots with raw clay materials and rice husks for water filtration. The basic raw clays have been mixed with rice husks at different ratio 10% and 15% weight (wt) and sintering at 1200&degC, 1300&degC and 1400&degC for 30 minutes. The elaborated pots have been tested for their densification properties and filtration flow. The mineralogy and microstructure of pot have been also studied to explain the different results. The pot with 10% wt rice husks and sintering at 1300&degC during 30 minutes presents a sufficient porosity and mechanical strength to be used for water filtration.
