Alterations in cordierite based burners subjected to radiant mode ageing conditions

Industrially developed perforated cordierite ceramic tiles were aged under accelerated conditions in a radiant combustion mode. Changes in the original phases, microstructure and mechanical properties were evidenced in the aged plates. The extent of the degraded zone was localized at the uppermost layer of the burner. These effects are attributed to corrosion of the cordierite-based material by gaseous species generated in the combustion.
