Abstract The aim of research was developed area of nanoporous ceramic matrials of ternary - ZrO2-TiO2-SiO2 system. The ceramic materials of system ZrO2-TiO2-SiO2 was synthesized via sol-gel technology by hydrolysis of tetraethylorthosilicate (TEOS), zirconia propoxide and titanium isporopoxide solutions. The sols were polymerized at room temperature to obtain gels. Then gels were dried at 100 OC 72 hours. Xerogel was milled 1 or 6 hours and the powder was axial pressed for nanoporous ceramic samples. All the samples were sintered at 800 OC or 1000 OC in air. 1M HYPERLINK "res://\\\\ld1062.dll/type=1_word=hydrochloric%20acid" hydrochloric acid (HCl) and destilled water were used as a catalyst to promote the hydrolysis and condensation reactions. All samples were characterized by X-rays (XRD) diffraction, particle size distribution and compressive strength. Apparent density and specific surface area of ceramic samples were determined by a Brunauer, Emmett and Teller (BET) nitrogen adsorption-desorption isotherms.
