MG4425 Magnesium Oxide Insulator, MgO

Magnesium Oxide Insulator Description

Magnesium Oxide Insulator is used to electrically isolate and mechanically support the thermoelements of a thermocouple. Its melting point (3098K) is the highest in the oxide. Magnesium oxide is superior in corrosion resistance in molten metal. Magnesium oxide can be used for a lot of metals compared with aluminum oxide.
