Molybdenum Disilicide Heating Elements

Products Description

Molybdenum Disilicide Heating Elements are made on the basis of molybdenum disilicide and are resistant to high temperatures and oxidation. When used in a high-temperature oxidizing atmosphere, they produce a bright, dense quartz (SiO2) glass film on the surface, which protects the inner layer of the silicon-molybdenum rod from oxidation, resulting in unique high-temperature oxidation resistance. Its general operating temperature range is 1600-1900°C. The resistivity of the element increases rapidly with increasing temperature.

Our Molybdenum Disilicide Heating Elements operate at high temperatures and are characterized by high temperature resistance, oxidation resistance, corrosion resistance, fast heating, long life, low deformation at high temperatures, and easy installation and maintenance. In addition, it also has good chemical stability and the complement is not easily deformed. It is widely used in metallurgy, steelmaking, glass, ceramics, refractory materials.

Attentions

1. This type of element should not be used in the temperature range of 400°C-700°C, because under such unfavorable conditions, the component will undergo low-temperature oxidation and cause damage to the component.

2. They are suitable for use in air and neutral air. Reducing the atmosphere (such as hydrogen) will destroy the protective layer, and chlorine and the sulfur vapor will directly damage these elements.

One of the methods to distinguish the new type and old type MoSi2 heating elements

Distinguish from the welding port:

The new process silicon molybdenum rod has high purity and high temperature resistance. When welding with a robotic arm at high temperatures, there will be a small bump at the welding point of the hot end and the cold end. The old one is low in purity, there is no bulge when welding, and there is a welding gap at the welding port. Therefore, whether it is a new process or an old process, it can be distinguished from a welding port.

Q&A

1. What is the working temperature?

The mainly working temperature ranges from 1600-1900℃. We will confirm your application and working environment before introducing our heating element to you.

2. What is the packing method?

The heater is usually packed by foam bag, then packed by exporting wooden cases. We also could pack the goods as per your requirements.
