U type Mosi2 Heating elemet

The U - type molybdenum disilicide heating element is a high - performance component of heating equipment.
I. Appearance and Structure
It features a unique U - shaped design. This shape not only saves space but also facilitates installation and layout in various heating devices. It is made of molybdenum disilicide, a material with special properties, and usually has a gray appearance with a certain metallic luster.
II. Material Properties
High Hardness: Molybdenum disilicide has a relatively high hardness with a Mohs hardness of approximately 7. This enables the heating element to withstand certain mechanical pressures and frictions during installation and use, making it less prone to physical damage and ensuring the durability of the product.
Good Antioxidant Properties: Under high - temperature conditions (generally within the range of 1000 - 1700°C), a dense silicon dioxide (SiO₂) protective film will form on its surface. This protective film can effectively prevent oxygen from further reacting with the internal molybdenum disilicide, thus ensuring excellent stability and a longer service life of the heating element in a high - temperature oxidizing environment.
High Thermal Conductivity: The molybdenum disilicide material has a relatively high thermal conductivity, enabling it to effectively conduct heat. During the heating process, heat can be quickly transferred within the heating element, reducing the phenomenon of local overheating and improving the uniformity and efficiency of heating.
Low Coefficient of Thermal Expansion: The coefficient of thermal expansion is relatively low. When the temperature changes, the size change of the material is relatively small. This helps maintain the shape and structural integrity of the heating element, reducing the risk of damage caused by thermal expansion.
