The Molybdenum Disilicide (MoSi2) Type U with Right Angle Heater is a high-temperature heating element designed for specific applications where furnace geometry or heat distribution requires an angular configuration. Manufactured from high-purity MoSi2, this MoSi2 heater combines the efficiency of the “U” shape with a right-angle section, allowing for precise adaptation to the internal contours of complex furnaces. It is a robust solution for environments demanding temperatures up to 1850°C, offering excellent oxidation resistance and a prolonged service life. As a high-temperature furnace heating element with an angled design, it is ideal for optimizing space and thermal uniformity in heating chambers with non-standard geometries.
A MoSi2 Type U heater with a right angle is a type of molybdenum silicon heating element that features a physical configuration in the shape of a "U" with one or more sections bent at a 90-degree angle. This geometry is particularly advantageous for installation in electric furnaces with corners or cavities, allowing the heater to conform to the furnace shape and maximize the effective heating surface. These MoSi2 heaters for industrial furnaces are known for their ability to withstand high surface loads and for their rapid heating, making them an efficient choice for processes that require fast heating cycles and extremely high temperatures. Its MoSi2 composition grants it unique corrosion resistance and high-temperature stability properties in oxidizing environments.
The MoSi2 Type U with Right Angle Heater is especially useful in industries and high-temperature processes where the furnace configuration requires heaters with specific shapes:
Laboratory and Experimental Furnaces: Where flexibility in furnace design is crucial for research and development.
Compact Sintering Furnaces: For the production of ceramic or metallic components in confined spaces.
Heat Treatment Furnaces with Specific Zones: Allows for more efficient heating of particular areas within a furnace.
Glass and Ceramic Industry: In furnaces with complex geometries for material processing.
Electronic Component Manufacturing: In high-precision furnaces for the production of semiconductors and other devices.

Adequate packaging for MoSi2 Type U heaters with a Right Angle is essential to guarantee their integrity during transport and storage, as they are fragile elements when cold. The following procedures are followed:
Individual Packaging: Each heater is individually packaged in protective material, such as polyethylene foam or air bubbles, to absorb impacts and vibrations.
Heavy-Duty Cardboard Boxes: The individually packaged heaters are placed in heavy-duty corrugated cardboard boxes, which provide an additional layer of protection.
Internal Cushioning: Additional cushioning material is used inside the boxes to ensure the heaters do not move and to protect the angled sections from potential damage.
Clear Labeling: Each box is clearly labeled with information about the contents, the heater type (MoSi2 Type U with Right Angle), handling instructions (FRAGILE), and storage precautions.
Palletization: For bulk shipments, the boxes are palletized and wrapped with stretch film to ensure stability and protection against moisture and dust.
Documentation: Technical documentation and installation/usage instructions are included inside the packaging or attached to the shipment.
This packaging method ensures that the molybdenum silicon heating elements with a right angle arrive at their destination in perfect condition, ready for installation and use.
The working temperature of MoSi2 heaters varies according to the furnace atmosphere:
• In air: up to 1700°C.
• In nitrogen: up to 1600°C.
• In hydrogen: between 1220°C and 1500°C.
It is crucial to select the appropriate heater for the specific atmosphere of your process to ensure the durability of the MoSi2 heating element.
