The magnesium oxide is used as a refractory under severe condition. Because its melting point (3099K) is the highest in the oxide and it is excellent in thermal conductivity (53W・m^-1・K^-1).
The magnesium oxide is superior in corrosion resistance in the molten metal. The magnesium oxide can be used for a lot of metals compared with the aluminum oxide. Especially, it is suitable for the calcination of lead zirconate titanate (PZT).
Tateho manufactures magnesium oxide ceramics products of various shapes, such as setters, crucibles and saggers in a continuous process from raw materials to products.

TATECERA® SMG Magnesium Oxide Setter

Tateho can produce the TATECERA® SMG magnesium oxide setter of various densities.
