O 13 (mullite) eutectic oxide was discovered by the authors in the Lu 2 O 3 -SiO 2 -Al 2 O 3 ternary system. The composition of the eutectic was Lu 2 O 3 :SiO 2 :Al 2 O 3 = 18.1:54.6:27.3 in molar ratio. The eutectic point was at approximately 1500-1550 β’ C. Since this eutectic system has no boundar
Water vapor corrosion of mullite single crystals and polycrystalline mullite ceramics was investigated in rapidly streaming water vapor at 1200 β’ C. Both materials behave quite differently: mullite ceramics display non-isotropic corrosive attack resulting in superficial β£-alumina formation with high
