In this work, nanoporous spinel/forsterite/zirconia ceramic composites were fabricated at 1600°C for 2h. The influence of zirconia content (up to 10mass%) on the technological properties, nanopores formation, phase compositions, microstructure and thermal diffusivity of nanoporous ceramic composites was investigated. Nanospinel and nanoforsterite powders were synthesized via a modified co-precipitation and sol–gel techniques, respectively. Results indicated that apparent porosity of the fired nanoporous ceramic composites is mostly in the range 14.26–56.14% with the average pores diameter 35.8nm. Using of nanopowders (spinel and forsterite) as the staring materials were achieved high mechanical (cold crushing strength∼235–164MPa) and elastic (Young’s modulus∼123.6–4.5GPa) properties of the prepared nanoporous ceramic composites. Microstructure analysis exhibited all of the crystalline phases and pores of the nanoporous ceramic composites are in the nanosize (35–40nm). These nanoporous ceramic composites are promising porous ceramic materials for using in advanced applications due to their excellent combination properties.
