High-Temperature Applications in Focus: Understanding and Preventing Spalling on MoSi₂ Heating Elements
Modern high-temperature processes must meet the most demanding requirements under extreme conditions. When operating molybdenum disilicide (MoSi₂) heating elements, one recurring issue—regardless of the manufacturer—is spalling.
A common cause: reducing atmospheres, which prevent the formation of a new protective SiO₂ layer on the element surface.
✅ Our recommended solutions if spalling occurs:
In general, the use of heating elements with a thicker SiO₂ protective layer can be considered in reducing atmospheres. We’re happy to advise you on the right option!
