· MgAlO3

MgAlO3 is a magnesium aluminate ceramic compound that forms part of the spinel-related oxide family, combining magnesium and aluminum oxides in a stable crystalline structure. This material is primarily investigated for high-temperature applications and refractory use, where its thermal stability and chemical resistance provide advantages in demanding environments such as furnace linings, kiln components, and metallurgical processes. Compared to pure alumina or magnesia refractories, magnesium aluminate offers improved thermal shock resistance and better performance in molten metal contact, making it attractive for industries requiring long service life in extreme thermal cycling conditions.
