High Temperature Silicon Molybdenum Rod
PRODUCT PARAMETERS
Description
High Temperature Silicon Molybdenum Rod
A high-temperature silicon molybdenum rod is a high-temperature heating element made primarily of molybdenum disilicide (MoSi₂). It possesses excellent high-temperature oxidation resistance and stable electrical resistance characteristics. Its maximum operating temperature can reach 1800℃, and it is widely used in high-temperature experimental furnaces, industrial kilns, sintering furnaces, heat treatment furnaces, and other equipment.
When operating in a high-temperature oxidizing atmosphere, a dense quartz protective film forms on the surface of the silicon molybdenum rod, effectively preventing further oxidation and extending the element’s lifespan. Simultaneously, the silicon molybdenum rod features rapid heating, high thermal efficiency, convenient installation, and stable resistance, making it a commonly used high-performance heating element in high-temperature electric furnaces above 1600℃.
