Process for preparing cordierite matrix ceramics is described. Thus, the process comprises i)mixing allumina sol and silica sol at a molar ratio of Al2O3 to SIO2 of 1.37-1.76, ii)mixing obtained mixture with dispersed solution of reinforcing agent such as SiC whisker and magnesia sol by turns to give a gel mixture, iii)drying and sintering at 300-500 deg.C.in a ball mill, and grinded. The process improves hardness of ceramic product.
