摘要：

Novel ceramics showing a high corrosion resistance were obtained by adding alkaline earth sulfates to mullite (Al6Si2O13). Powder samples of mullite, mullite-SrSO4 and mullite-BaSO4 were prepared. Disk pellets of 4 cm in diameter were conformed by uniaxial pressing at 78 MPa and sintered at 1450 degrees C for 6 h. Wetting experiments were carried out by the sessile drop test at 900 degrees C using an Al-7Mg alloy. After sintering, substrates of mullite, mullite-SrAl2Si2O8 or mullite-BaAl2Si2O8 were obtained. The contact angles between samples surface of alkaline earth sulfates containing mullite and molten alloy were higher than that corresponding to pure mullite, showing a non-wetting behavior. Cross-section analysis by SEM and EDS of samples after the wetting test showed that the corrosion products were spinel (MgAl2O4) and periclase (MgO). The BaAl2Si2O8-containing samples showed a higher corrosion resistance. (C) 2015 Elsevier Ltd. All rights reserved.
