Magnesia Ceramics

Magnesium oxide ceramics has high melting point, high hardness, corrosion resistance and chemical stability.The following are the applications:

1.Refractory materials: This is the most significant application field of magnesium oxide. MgO has an extremely high melting point (approximately 2800℃) and excellent thermal shock resistance, making it an outstanding refractory material and widely used in:

Steel smelting: Used as the inner lining of steel-making furnaces, ladle inner lining, etc.
Non-ferrous metal smelting: Furnace linings used for smelting non-ferrous metals such as copper and aluminum.
Glass industry: It is used as the inner lining of glass furnaces because it has good corrosion resistance to molten glass.
Cement industry: Used as lining for cement rotary kilns.

2. Electric heating elements: MgO has excellent electrical insulation and high thermal conductivity, and thus is commonly used as an insulating material in electric heating elements, for example:

Heating tube: MgO powder is filled in the metal tube, serving as the insulating layer of the resistance wire.
Thermocouple: MgO is used to protect the temperature measurement element of the thermocouple.
Substrate: MgO substrates have excellent heat resistance and electrical insulation,
