| Abstract Scope |
Utilization of wastes and local raw materials for the synthesis of porous ceramics is a vital path towards achieving environmental sustainability. In this study porous ceramics were developed from a mix of granite powder, ball clay and plantain peel powder with the addition of NaOH and Na2SiO3 as sintering aid. Chemical analysis of the raw materials was carried out using X-ray Fluorescence spectrometry. The mixes obtained were uniaxially pressed at 10MPa and sintered at 8500C. The results of the physical and mechanical properties of the developed porous ceramics revealed water absorption (19.5-41.7%), bulk density (1.39-1.86g/cm3), apparent porosity of (36.4-66.7%) and compressive strength (0.9-18.4MPa). The X-ray Diffraction analysis of the representative sample showed anorthite, sodalite and afghanite crystalline phases. The microstructural analysis of the representative sample revealed inhomogeneous and open-celled morphology. The developed porous ceramics is a promising material for use in separation / filtration application given its unique mineralogical phases. |
