Molybdenum‐doped cordierite ceramics have been fabricated through facile combined techniques, coprecipitation followed by solid state. XRD results revealed that α‐cordierite phase is predominated with increasing M o 6+ ion content. The density measurements showed that the bulk density reduced to the minimum value of 0.61 g/cm 3 , which corresponds to the maximum porosity of about 76.8% at 5% M o 6+ ion. The dielectric permittivity (ε) of pure cordierite is decreased with increasing M o 6+ ion content. The minimum dielectric loss of M o‐doped cordierite at 1 MH z was equal 0.008 with 10% M o 6+ , while at 1 GH z was equal 0.03 with 5% M o 6+ .
