What are the types of heating rods for high-temperature sintering furnaces?

There are various types of heating rods for high-temperature sintering furnaces, each with different characteristics and applicable scenarios. Here are some common types of heating rods:
Metal heating rod:
Material: Commonly used metals include stainless steel, iron chromium aluminum, molybdenum, tungsten, etc.
Features: High temperature resistance, not easy to rust, fast heating speed. However, it should be noted that they may not be resistant to corrosion and oxidation, making them more suitable for some relatively clean heating applications.
Silicon molybdenum rod:
Features: Silicon molybdenum rod is a high-temperature heating element, especially suitable for high-temperature sintering furnaces. It has a high melting point, good oxidation resistance, and thermal stability, and can maintain stable heating performance at extreme high temperatures.
Application: Silicon molybdenum rods are commonly used heating elements in high-temperature sintering furnaces at 1700 degrees Celsius.
Silicon carbide:
Features: Silicon carbon rod is a composite material made from a mixture of organic silicon and carbon. It has excellent conductivity and thermal conductivity, good high-temperature corrosion resistance, and fast heating speed. However, its price is also relatively high.
Application: Silicon carbon rods are suitable for some special high-temperature heating applications, such as sintering furnaces at 1400 degrees Celsius.
In summary, there are various types of heating rods for high-temperature sintering furnaces, and each material has its unique advantages and applicable scenarios. When choosing a heating rod, it is necessary to consider the specific heating conditions, requirements, and process needs comprehensively. For example, if the sintering furnace needs to reach extremely high temperatures, silicon molybdenum rods may be a better choice; If corrosive substances need to be processed in the sintering furnace, it may be necessary to consider using heating rods with better corrosion resistance.
