Development and evolution of a novel (Zr1-xSnx)O2 toughened alumina-mullite slip cast refractory: Effect of SnO2

Static and dynamic corrosion behavior of SnO2‐doped AZS slip cast refractory in SLS glass

“…It is also known that a change of refractory design is an additional possible way of improving the wear/dissolution rate of refractory grains/matrix in glass melts. Authors of the current study demonstrated in a previous investigation the effects of SnO 2 in producing a dense slip cast refractory with a SnO 2 ‐ZrO 2 solid solution reinforced and interlocked acicular mullite microstructure 20 . In the study, the authors also briefly demonstrated the reduced solubility potential of Zr (1‐x) Sn (x) O 2 solid solution grains in SLS glass and with it the potential for improved corrosion resistance of the refractory in SLS glass 20 .…”

“…In this study, the corrosion behavior and corrosion resistance of AZS‐T1, an optimized Zr (1‐x) Sn (x) O 2 solid solution reinforced alumina‐mullite refractory brick, in contact with SLS glass were investigated under both isothermal static and dynamic corrosion test at 1370˚C for 72 h. The crucible/cup test method was used for the static corrosion test, while the rotary finger test was used for dynamic corrosion tests, following a variant of the ASTM C‐621 method. The particle packing optimization and synthesis of the SnO 2 ‐doped AZS refractory, AZS‐T1, is covered in detail in our previous study 20 …”
