Abstract Samples of montmorillonite/α-naphthylamine complex (MNC), saponite/α-naphthylamine complex (SNC) and their mixtures were heated at temperatures below 1473 K under a nitrogen atmosphere to examine macroscopic structural change and crystalline phases deposited after pyrolysis. SNC resulted in a dense structure after pyrolysis. Heating of samples of MNC/SNC mixtures gave a porous structure which became dense as the proportion of SNC increased. No porosity measured by the mercury porosimeter was detectable in samples pyrolysed from MNC containing more than 25% SNC. After pyrolysis, the MNC/SNC mixtures gave crystalline phases which were never formed in the pyrolysed pure MNC and SNC. The formation of these crystalline phases was explained by reference to the chemical compositions of the mixtures and the phase diagram.
