Silicon - molybdenum rods and silicon - carbon rods are mainly used as heating elements in high - temperature electric furnaces. They can maintain stable performance in a high - temperature environment and ensure uniform temperature inside the furnace, meeting various process requirements.

Applications of Silicon - Molybdenum Rods in High - Temperature Electric Furnaces

Silicon - molybdenum rods are a type of high - temperature - resistant and antioxidant resistance - heating element made on the basis of molybdenum disilicide. When used in a high - temperature oxidative atmosphere, a bright and dense quartz (SiO₂) glass film is formed on the surface, which can protect the inner layer of the silicon - molybdenum rod from further oxidation. Therefore, silicon - molybdenum rod elements have unique high - temperature antioxidant properties. Silicon - molybdenum rods are widely used in fields such as metallurgy, steel - making, glass, ceramics, refractory materials, crystals, electronic components, semiconductor material research, production and manufacturing, especially for the production of high - performance precision ceramics, high - grade artificial crystals, precision - structured cermets, glass fibers, optical fibers and high - grade alloy steels.

Applications of Silicon - Carbon Rods in High - Temperature Electric Furnaces

Silicon - carbon rods are non - metallic electrothermal elements made mainly from high - purity green hexagonal silicon carbide. They have the characteristics of high - temperature resistance, antioxidant, corrosion - resistance, fast heating - up, long service life, small high - temperature deformation, and convenient installation and maintenance. Silicon - carbon rods are now widely used in high - temperature fields such as electronics, magnetic materials, powder metallurgy, ceramics, glass, semiconductors, analysis and testing, scientific research, etc., and have become electro - heating elements for tunnel kilns, roller kilns, glass kilns, vacuum furnaces, muffle furnaces, smelting furnaces and various heating devices.

Factors to Consider When Selecting Silicon - Molybdenum Rods and Silicon - Carbon Rods

When choosing to use silicon - molybdenum rods or silicon - carbon rods, the following factors need to be considered:

1.Operating temperature: Silicon - molybdenum rods can be used at higher temperatures, with a maximum operating temperature of up to 1800°C, while the operating temperature range of silicon - carbon rods is usually between 1000 - 1450°C.

2.Antioxidant property: Silicon - molybdenum rods have better antioxidant properties in a high - temperature oxidative atmosphere because a dense quartz glass film is formed on their surface.

3.Chemical stability: Silicon - carbon rods have good chemical stability, especially excellent acid - resistance performance.

4.Application fields: Select appropriate heating elements according to specific application fields and process requirements. For example, in situations where higher temperature and antioxidant properties are required, silicon - molybdenum rods may be more suitable; while in fields with high requirements for chemical stability and acid - resistance performance, silicon - carbon rods may be a better choice.
