Molybdenum disilicide tubes

Types of Molybdenum Disilicide Tubes

Molybdenum disilicide (MoSi2) is an important chemical compound that is widely used for various industrial applications. MoSi2 offers great benefits in high-temperature resistance and can be used as a heating element or protective coating.

Molybdenum disilicide tubes have a variety of uses. MoSi2 supports the heating elements in vacuum and inert gas environments and galvanizes the metal industry. The tubes also make up a part of the semiconductor and lighting industry. They are often used to make the electrode holders, igniters, and lamp tubes.

Molybdenum disilicide tubes come in different shapes and sizes, as demanded by specific industries. Some of them are:

• Molybdenum disilicide protective tube

  The protective tube provides a shelter and protects the SiC heating element from oxidizing. It is also used to safeguard the material in high-temperature and reactive environments. There are multiple kinds of MoSi2 protective tubes. For example, the molybdenum disilicide sialon tube is frequently used in sialon tube applications. Sialon tubes can work well in oxidizing ambient conditions at about 2000 degrees centigrade. It can also restrain the deposit and sulfide, making it a suitable option for the steel making industry.

• Molybdenum disilicide lamp tube

  For lamp manufacturing industries, the MoSi2 lamp tube is a great choice. It has good thermal conductivity and can resist high temperatures. The lamp tube easily protects the gas discharge in the lamp. It also contributes to the stability and reliability of the electrical performance.

• Molybdenum disilicide electrode holder

  Electrode holders made from MoSi2 are commonly used in electric arc furnaces. They have a good hold on the electrodes and provide steady electrical conductivity. MoSi2 holder tubes are also used in welding applications. They offer precise electrode positioning and smooth electrical flow.

• Molybdenum disilicide igniter

  Molybdenum disilicide igniters are used in combustion engines and gas burners. They support fast and reliable ignition. MoSi2 igniters enhance the performance and fuel efficiency of automobiles and machinery.

Specification and Maintenance of Molybdenum Disilicide Tubes

• Length: The length forms of Molybdenum Disilicide heater tubes according to the needs of the furnace lining. They can be cut and customized up to about 3 meters in length.
• Inner Diameter: The inner diameter of the tube affects the amount of material that can be heated and the rate of heat transfer. The typical inner diameter is 0.5-3 inches (12-76 mm).
• Wall Thickness: The wall thickness of the tube affects the strength, durability, and heat transfer characteristics of the tube.
• Material composition: The material composition of the MoSi2 heater tube affects the performance of the tube, including temperature resistance, oxidation resistance, and thermal conductivity.
• Design features: Molybdenum disilicide tubes may have some design features, such as grooves, notches, flanges, etc., which are used to connect, fix, or transfer electrical connections with other components.

Maintenance

• Regular cleaning: Clean the surface of the heater tube regularly to remove dirt, grease, etc. Use a mild detergent and warm water to clean, avoid using harsh chemicals or abrasive cleaners, and ensure that the tube is completely dried before use.
• Avoid direct contact with corrosive substances: Keep the tubes away from corrosive substances, such as acids and alkalis, to avoid chemical reactions or damage.
• Avoid mechanical damage: Avoid mechanical damage, such as dents, deformities, etc. When installing, removing, or handling the heater tube, pay attention to the handling carefully.
• Temperature control: Control the operating temperature. Molybdenum disilicide tubes can withstand a high temperature, but prolonged exposure to excessively high temperatures may accelerate their aging and deterioration.
• Replace damaged parts: If damaged parts, such as cracks, deformations, etc., promptly replace them to ensure the continued performance and safety of the equipment.

Scenarios of Molybdenum Disilicide Tubes

Molybdenum disilicide (MoSi2) tubes are widely used in the semiconductor and electronics industry. In the semiconductor industry, MoSi2 tubes are often used as transfer tubes, protective tubes, and boats for transporting semiconductor wafers in furnace heating elements. These tubes act as a barrier to protect the wafers from contamination during the heating process. Molybdenum disilicide tubes' high-temperature stability and low distortion make them an ideal choice for this application.

In the ceramics industry, MoSi2 tubes are used as part of the support structure and protective elements in high-temperature ceramic furnaces. They provide support for the heating elements in these furnaces, which operate at very high temperatures. Additionally, MoSi2 tubes protect the fragile ceramic components from thermal shock and mechanical damage. This is due to their ability to withstand high temperatures and resist thermal expansion, which minimizes the risk of cracking or breaking.

Moreover, in the metallurgy industry, MoSi2 tubes are used as furnace shrouds, protective tubes, and electrode holders in high-temperature metallurgy furnaces. They protect the delicate ceramic and quartz lighting elements from heat and electrical current. The protective tubes act as a barrier to prevent arc strikes and imprecise metal pouring, thus ensuring safety and precision during high-temperature metal processing operations.

In the lighting industry, MoSi2 tubes are used in high-pressure sodium lamp furnaces. They serve as the heating element support and enable the proper positioning of the gas discharge tube within the lamp. Molybdenum disilicide tubes provide the necessary thermal energy to initiate the chemical reactions inside the discharge tube, thus facilitating the lighting process.

Finally, in the optical fiber production industry, MoSi2 tubes are used as fiber optic drawing towers. They are essential molds in the process of fiber optic production. Molybdenum disilicide tubes provide the high-temperature environment and the precise control needed to produce high-quality fiber optic cables, which are crucial for telecommunications and data transmission.
