MU1766 W-type Molybdenum Disilicide (MoSi2) Heating Rods

W-type Molybdenum Disilicide Heating Rods Description

The W-type Molybdenum Disilicide Heating Elements are known for their longevity and reliability at a high temperature. The W-type heating rod is generally placed horizontally. Due to the more heat-generating end, its heating efficiency is higher and cost-effective than other heating elements. This heating element consists of 2 cold ends (Lu), 3 or more U-shaped hot zone (Le). In usually, the Lu has a twice diameter of Le.  

MoSi2 Heating Elements are manufactured by powder metallurgy. They consist of molybdenum disilicide and additives to prevent recrystallization. Because MoSi2 is completely stable at 1800ºC (3270 ° F), it has a higher temperature performance than other types of heating elements. The resistance of the MoSi2 element to oxidation lies in the formation of impermeable quartz or glass-like protective layer, which will be re-formed upon heating if it is damaged during operation.

MoSi2 devices have low resistivity and have positive resistance-temperature characteristics. Compared to metal heating elements, it can be used under very high watt loads. Due to its high-temperature oxidation resistance, MoSi2 resistors remain constant at a constant temperature throughout their useful life. Even in series, new and old components can be used simultaneously in the same furnace.

FAQs

Q1: What are W-type Molybdenum Disilicide Heating Rods?

W-type Molybdenum Disilicide (MoSi₂) Heating Rods are high-temperature heating elements made from molybdenum disilicide, designed in a "W" shape (often referring to the physical configuration of the rod). These rods are commonly used for applications that require stable, high-temperature heating, such as furnaces and kilns, offering superior thermal performance.

Q2: What are the key properties of W-type Molybdenum Disilicide Heating Rods?

• High Temperature Resistance: Can withstand extremely high temperatures, up to 1800°C (3272°F), ideal for demanding industrial applications.
• Efficient Heat Distribution: The "W" shape helps provide uniform heating by optimizing the surface area exposed to heat.
• Oxidation Resistance: Forms a protective oxide layer when heated, which helps protect the material from oxidation even in harsh environments.

Q3: What are the applications of W-type Molybdenum Disilicide Heating Rods?

• High-Temperature Furnaces: Used in industrial furnaces for heat treatment of metals and ceramics, where high temperature stability is critical.
• Ceramic Kilns: Used for firing and sintering ceramics, as the W-shape allows for better fit and heat distribution in specific kiln designs.
• Glass Manufacturing: Ideal for use in glass melting furnaces and other glass production processes due to its high-temperature capabilities.
• Semiconductor Industry: Applied in processes like semiconductor wafer annealing, where precision heating is required.
