MG4431 Dense Magnesium Oxide Ceramics
Dense Magnesium Oxide Ceramics Description
Dense Magnesium Oxide Ceramics are used as a refractory under severe conditions because their melting point (3098K) is the highest in the oxide. Magnesium Oxide is superior in corrosion resistance in molten metal. Magnesium Oxide Ceramics can be used for a lot of metals compared with Aluminum Oxide Ceramics.
