The effects of pre-sintering temperature and La2O3 addition on sinterability and corrosion resistance of stoichiometric magnesium aluminate spinel

Optimization of corrosion resistance and mechanical properties of Al2O3‐Cr2O3 refractories for waste incinerator

“…13 It is well known that grain boundary, pores and cracks are the major channels for slag corrosion and penetration in refractories. [14][15][16] A great deal of researches focused on the porosity and densification of materials due to the existence of penetration channels. For example, research by Kim et al indicated that the local corrosion tended to occur around the pores in Al 2 O 3 ceramics.…”

“…In addition to physical effects such as mechanical scouring and thermal stress, the chemical corrosion is also main reason for refractories damage 13 . It is well known that grain boundary, pores and cracks are the major channels for slag corrosion and penetration in refractories 14–16 . A great deal of researches focused on the porosity and densification of materials due to the existence of penetration channels.…”
