MoSi2 Heating Rods

1. Product description

A key advantage of these elements is their superb oxidation resistance. When heated, they form a self-healing, adherent layer of silica that prevents further oxidation of the inner material, ensuring a long operational lifespan.

4. Why choose us?

1) Features

Stable Electrical Resistance Characteristics: They maintain relatively stable electrical resistance throughout their lifespan when operated within recommended parameters. This stability ensures consistent performance and reliable temperature control for your processes.

2) Applications

High-Temperature Testing Equipment: They are employed in specialized testing equipment where extreme temperatures are required. This includes creep testing, fatigue testing, and other material evaluation processes under thermal stress conditions.

3) Packaging

Efficient Palletization for Bulk Orders: For large orders, we carefully stack boxes on reinforced wooden pallets. These are stretch-wrapped and banded to create secure, stable units that facilitate easy forklift handling and loading.

4) Advantage

Superior High-Temperature Performance: Our MoSi₂ heating elements are engineered to operate continuously at extreme temperatures up to 1800°C in air. This exceptional performance ensures reliable and efficient thermal processing for your most demanding industrial applications, guaranteeing consistent results.

5. FAQ

1) Formation of Protective Layer
Q: What is the glossy glassy layer that forms on the surface?
A: That is the protective silica (SiO₂) layer that forms in oxidizing atmospheres. It is vital as it seals the interior material from further oxidation, thereby extending the element's life.

2) Causes of Premature Failure
Q: What typically causes these elements to fail prematurely?
A: Common causes include operating in the wrong atmosphere, thermal shock from rapid cooling, physical damage, operating above the maximum temperature, and contamination from furnace vapors.

3) Compatibility with Controllers
Q: What type of power control system is required?
A: You need a temperature controller with SCR (Silicon Controlled Rectifier) power regulators that are specifically configured to handle the low initial resistance and high cold current of these elements.

4) Storage Recommendations
Q: How should I store spare elements?
A: Keep them in a dry, temperature-stable environment in their original packaging. Avoid any moisture, as water absorption can cause cracking when the element is first heated.

5) Custom Shapes and Sizes
Q: Can you manufacture custom shapes like U-shaped or W-shaped elements?
A: Yes, we specialize in producing custom elements. We can manufacture various diameters, hot zone lengths, and pre-formed shapes like U, W, or hairpin to fit your specific furnace.
