A comparative study of the solid‐state reaction synthesis of cordierite with and without the use of a flux was performed, varying the sintering temperatures between 900° and 1400°C. Bi 2 O 3 proved to be a useful additive for lowering the temperature needed for the reaction to take place. The deviation from the ordered β‐cordierite phase was analyzed using the distortion index Δ as a factor of merit. The values obtained for Δ in all compositions showed that cordierite tended to a much‐ordered structure with increased sintering temperatures.
