Product Description

SPK MoSi₂ heating element

The MoSi₂ resistive heating element is based on molybdenum disilicide, a material known for its unique properties. When exposed to high-temperature oxidizing environments, a layer of lustrous and compact quartz (SiO₂) glass film is formed through a specific chemical reaction. This film acts as a shield, preventing oxidation of the inner silicon molybdenum rod and ensuring long-lasting high-temperature oxidation resistance.
The material structure of MoSi₂ is highly stable at high temperatures. It can withstand prolonged exposure to extreme heat without significant degradation in physical or chemical properties, guaranteeing the reliability and longevity of the heating element.

Chemical Resistance	Resistant to most acids and alkalis
Density	7.4 g/cm³
Flexural Strength	25 MPa
Corrosion Resistance	Highly resistant to oxidation and corrosion
Shape	Rod
Size	Customizable

Precautions for MoSi2 elements

MoSi₂ heating elements should never be utilized within the temperature range of 400 ℃ to 700 ℃ as it can lead to low-temperature oxidation and damage to the elements in such adverse conditions.
These elements are meant for use in air and neutral atmospheres. Reducing atmospheres like hydrogen will harm the protective layer, and chlorine and sulfur vapor will directly damage the elements.
MoSi₂ heating elements soften at high temperatures exceeding 1500 ℃ and are hard and brittle at low temperatures. To avoid stress caused by temperature changes and facilitate the expansion and contraction of the elements, the free vertical hanging installation method is preferred. This makes the removal and replacement of lifting elements more convenient and enables heat exchange without waiting for the furnace to cool down.
