Abstract

In the work, an analysis of the phase formation process proceeding in a quaternary red clay–low-melting cullet–iron oxide (Fe2O3)–WAS (waste activated sludge) system in treatment at 1000oC in air has been performed. It has been established that, in sintering of the mixtures, porous ceramics consisting of a glass phase alloyed with iron ions with inclusions of cristobalite, iron-containing silicates of complex composition, α-Fe2O3, and an insignificant amount of Fe3O4 forms. The porous glass ceramics meets the compressive strength requirements imposed on building bricks.
