Abstract

Refractory cordierite ceramic using amorphous rice husk silica was modified by addition of periclase from 5 to 20% by weight, followed by sintering treatment at temperature of 1230 oC. The phases, structural changes and microstructure characteristics of samples were investigated by x-ray diffraction (XRD), scanning electron microscopy (SEM). The results obtained indicated the significant role of periclace addition on the phase decomposition of cordierite into spinel and forsterite. Addition of periclace was found to increase forsterite and decrease spinel. Formation of spinel and forsterite was followed by decrease in electrical resistivity, porosity and by increase density.
