Product Description

MoSi₂ heating elements (molybdenum disilicide heaters) deliver exceptional performance in high-temperature industrial processes. With a density of 5.5 g/cm³, these disilicide-molybdenum heaters are ideal for sintering ferrites, technical ceramics, refractories, and glass manufacturing applications. They operate reliably in continuous or periodic cycles within neutral, vacuum, or oxidizing atmospheres at temperatures up to 1800°C.

A key advantage of MoSi₂ heaters is the self-forming protective silicon dioxide (SiO₂) layer that prevents further oxidation, ensuring long service life and thermal stability.

Physical Properties of MoSi₂ Heating Elements

Volume Density	Bending Strength	Vickers Hardness	Porosity	Water Absorption	Hot Extensibility
5.5~5.6 kg/cm³	15-25 kg/cm³	(HV) 570 kg/mm²	7.4%	1.2%	4%

Chemical Properties & Operating Guidelines

MoSi₂ heating elements are designed for high-temperature use in oxidizing environments. The protective SiO₂ layer prevents melting and degradation. However, prolonged use between 400°C and 700°C must be avoided, as this temperature range promotes accelerated oxidation and potential damage.

Key Advantages of MoSi₂ Heaters

Self-Protecting Oxidation Resistance: SiO₂ film ensures longevity
Positive Temperature Coefficient: Resistance increases with temperature, enabling faster heating
Stable Electrical Resistance: Simplifies replacement and system integration
High Power Density: Efficient heating in compact furnace designs
