Key Features & Benefits: Why Choose KINTEK MoSi2 Elements?
KINTEK's MoSi2 Heating Elements are renowned for their exceptional performance, offering significant advantages for your high-temperature applications:
- Extreme Temperature Capability: Operate efficiently at temperatures up to 1800°C (and even 1900°C in specific oxidizing atmospheres), ideal for processes requiring intense heat. The maximum operating temperature under an oxidation atmosphere is 1800 ℃.
- Superior Oxidation Resistance: When heated in an oxidizing atmosphere, a protective, dense silica (SiO2) glass film forms on the surface. This layer safeguards the inner MoSi2 material from further oxidation, ensuring unique high-temperature oxidation resistance and extended element life.
- Stable and Reliable Performance: The resistance of MoSi2 elements increases with temperature, stabilizing when the temperature is constant. This stable resistance allows for consistent heating and the ability to connect new and old elements in series without compromising performance.
- Long Service Life: With proper selection of surface load and operating conditions, our MoSi2 elements offer the longest inherent life among many electric heating elements, providing a cost-effective solution by minimizing replacements and maintenance.
- Resilience to Thermal Cycling: These elements can withstand rapid thermal cycling without significant degradation, crucial for processes involving frequent temperature changes.
- Ease of Replacement: Designed for convenience, MoSi2 elements can often be replaced even while the furnace is hot, minimizing operational downtime.

Understanding MoSi2 Element Models & Dimensions
To specify the correct MoSi2 heating element, please refer to the following model marking convention:
- D1: Hot zone diameter
- D2: Cold zone diameter
- Le: Hot zone length
- Lu: Cold zone length
- A: Gap distance (shank spacing)
Standard model number format: D1/D2*Le*Lu*A
For example: If D1=6mm, D2=12mm, Le=200mm, Lu=300mm, A=30mm, the model is specified as: 6/12*200*300*30mm
Commonly available dimensions (custom sizes available upon request):
| D1 | D2 | Le Range | Lu Range | A (Typical) |
|---|---|---|---|---|
| 3mm | 6mm | 80-300mm | 80-500mm | 25mm |
| 4mm | 9mm | 80-350mm | 80-500mm | 25mm |
| 6mm | 12mm | 80-800mm | 80-1000mm | 25-60mm |
| 7mm | 12mm | 80-800mm | 80-1000mm | 25-60mm |
| 9mm | 18mm | 100-1200mm | 100-2500mm | 40-80mm |
| 12mm | 24mm | 100-1500mm | 100-1500mm | 40-100mm |
