Abstract

The results of petrographic studies of structure formation and the formation of the phase composition of the developed aluminophosphate refractory adhesive compositions Al2O3*-Cr2O3-H3PO4 at different temperatures with the addition of clay components are presented. It has been established that polarizing cristobalite tridymite and AlPO4 crystals of rhombic modification are observed in the phase composition of the composition of fired samples, which are thermally stable compounds that provide high performance properties when gluing refractory materials.
