Fused Magnesium Oxide Features
Fused Magnesium Oxide stands out for its high purity, large crystal size, and dense structure. Thanks to its exceptional purity and compactness, it offers excellent slag resistance and outstanding thermal shock stability. This makes it an ideal material for high-temperature electrical insulation and thermal conductivity applications.
Fused Magnesium Oxide Applications
Fused Magnesium Oxide plays a crucial role in the field of high-temperature electrical insulation.
In tubular heating elements, it’s packed between the heating wire and the metal sheath, providing effective insulation to prevent leakage and short circuits. At the same time, its superior thermal conductivity helps transfer heat outward efficiently, boosting the overall heating performance. Everyday appliances like electric kettles and space heaters rely on it for safe and efficient operation.
Beyond that, Fused Magnesium Oxide is also used as an insulating layer in high-temperature electrical wires and cables, ensuring electrical safety even at elevated temperatures. In places with strict fire safety requirements—like high-rise buildings and subways—it serves as a fire-resistant protective layer for cables.
In high-temperature industrial equipment, such as ceramic kilns and glass furnaces, Fused Magnesium Oxide is used for electrical insulation and as a thermal barrier in furnace linings. This helps reduce heat loss and improve thermal efficiency.
