Magnesia crucibles have found application in the superalloy industry, nuclear industry and chemicals industry where corrosion resistance is required. Manufacture is by firing isostatically pressed or slip cast shapes made from fused magnesia. Various purity grades are available. Additives are employed to promote sintering or restrict crystal growth. These range from clay to yttria and alumina depending on application. Crucibles with stability of 2400oC in air, 1700oC in reducing atmospheres, 1600oC in vacuum and 1400oC in hydrogen have been reported in the literature.
Magnesia ceramic is a ceramic material consisting of at least 90% of Magnesium Oxide(MgO).
It demonstrates good mechanical strength and operates well when uniformly heated or cooled and thermal shock is avoided. It offers superior performance to Alumina, being stable to 2200°C. However, above this temperature creep occurs. Due to its resistance to Lead-based materials, it is used for piezoelectric materials processing.
