A series of Ca2+-doped cordierite ((Mg1-xCax)2Al4Si5O18) ceramic powders were prepared by a sol-gel method. The effect of the substitution of Ca2+ for Mg2+ of cordierite ceramics on the sintering properties, structural characteristics, microwave dielectric properties and fracture toughness was investigated. The results show that the introduction of Ca2+ can improve the sintering activity of the powder, thus improving the density of the sample and the sintering densification. The single α-cordierite phase is obtained in the range of 0
