โœฆ Synopsis

Pure cordierite and cordierite-zirconia (5 and 15 mol.%) are prepared by an aqueous sol-gel technique starting from aqueous solutions of magnesium formate, aluminium formate, zirconium formate and tetraethoxysilane. The gels are dried and calcined at different temperatures ranging from 600 to 1300ยฐC. The dried gels and calcined powders are characterized by thermogravimetric analysis, differential thermal analysis, X-ray powder diffraction and infrared spectroscopic analysis.

Composite materials with 85 to 65 wt% cordierite and 15 to 35 wt% Zr02 were prepared from co-precipitated cordierite powder, and their densification behaviour, microstructure, mechanical strength, fracture toughness, thermal expansion and thermal shock resistance were studied. Addition of Zr02 to pu
