Abstract

Highly porous kaolin ceramics composites were produced by adding space-holder materials during dry pressing. To increase the strength of porous kaolin ceramic composites different ratios of cobalt-nickel ferrite nanoparticles (5, 10, 15, and 20%) were added. The sol-gel auto-combustion method prepared the nano cobalt-nickel ferrite particles (CNF). Space-holder materials were removed by preheating, and solid specimens were produced by sintering. X-ray diffraction (X-RD) and Fourier transform infrared spectroscopy (FT-IR) was used to examine the structural characteristics. Up to 47.05% porosity was achieved when 20% CNF was added to the porous kaolin ceramics composites. The results indicated that the higher percentages of nano CNF 20% decreased linear shrinkage and the loss of ignition by 4.4% and 30.4%, respectively. While increased apparent density and diametrical strength of 1.42 g/cm3, and 9.03MPa respectively. Diametrical strength nanoparticles increased the strength attributed to the formation of a secondary phase in the porous ceramics, improving the crack bridging mechanism.
