Conclusions We have examined some well known reactions of the synthesis of cordierite from natural materials and alumina. The volume changes occurring during these reactions, the yield of cordierite, and the value of the Gibbs free energy have been calculated. It is established that the most favorable method under industrial conditions is to synthesize cordierite from a stoichiomeric mixture of talc, kaolin and alumina. The phase composition of the cordierite sinters based on these materials has been studied. The synthesis of cordierite can be done in the presence of Al2O3-containing components on condition that the firing temperature does not exceed 1659°K when the sintering of the materials is effected in parallel. X-ray and IR-spectrometric studies were carried out on the chamotte and corundum-corderite materials confirming the coexistence of corundum and cordierite as two noninteracting phases at T≤1659°K.
