Abstract The aim of research is to develop an area of nanoporous ceramics of ternary systems. Nanoporous ceramic system SiO2-TiO2-ZrO2 has been synthesized via sol-gel technology by hydrolysis of tetraethylorthosilicate (TEOS), zirconia and titanium alcoxides solutions. The sols have been polymerized at room temperature to obtain gels and dried at 100 oC, then milled for 1 or 6 hours for particle homogenization, pressed into samples, and then sintered at 800 oC or 1000 oC in air. The samples have been characterized by XRD, particle size distribution, crystallite size distribution, compressive strength. Porosity of ceramic samples has been determined by nitrogen adsorption-desorption isotherms.
