Aremco Products, Inc.'s new Super-Heat(TM) 676 MgO ceramic is a full-fired, 99% pure material used in applications to 4000F (2200C). The material is a high-density, fine-grain microstructure with an open porosity of less than 1% and an average density of 3.45 gms/cc or 96% of theoretical. This ceramic is an ideal alternative to alumina because it exhibits better chemical resistance and is inert to metals, slags and superconductor compounds. Crucibles are currently available in both stock and custom shapes up to 7 in. diameter by 12 in. length, with a wall thickness of 0.2 in. maximum.
