Silicon Carbide Heating Elements

Silicon carbide (SiC) heating elements are popularly found in high temperature electric furnaces, where they can be mounted horizontally or vertically for use.

Globar SiC heating elements feature hot zones of dense recrystallized silicon carbide that have been optimized to resist oxidation and chemical attack from process volatiles and reactive environments. They come with either single- or multi-leg designs.

SC Type

The SC Type silicon carbide heating element features a hollow tubular heating part with thickened ends to withstand sudden changes in cold and heat without deforming, making it suitable for high-temperature box furnaces that require precise temperature control.

These elements are constructed using recrystallised green high-purity hexagonal silicide, a chemically stable material with an extremely low thermal expansion coefficient and high resistance, making them perfect for use in high temperature industrial furnaces and metal heat treatment applications.

Heating elements offer many advantages, including being able to withstand temperatures up to 1627 degC and resist chemical attack from process volatiles and reactive atmospheres. Furthermore, their lower thermal capacity compares favorably to many other industrial heating elements in terms of preventing excessive heat loss while improving energy efficiency and prolonging their service lives. Finally, their resistance to corrosion helps prolong service lives further still.

H Type

H Type silicon carbide heating elements are non-metallic high temperature electric furnace heaters made of green (beta) silicon carbide as the main material. When heated at high temperatures and recrystallized into fine grains for heat transfer purposes, electrical energy can be converted to thermal energy through Joule’s Law which states: W=I2R.

Heating elements consist of a central heating section known as the hot zone and two terminal sections known as cold ends infused with aluminum for low resistance contact surfaces that connect directly to power supply via braided aluminum straps.

Silicon carbide heating elements come in various styles, each specifically tailored for specific industrial uses. For instance, SC Type elements with their single spiral configuration provide durable and effective heat distribution while W Type models deliver reliable performance in continuous high temperature environments.

W Type

Silicon carbide (SiC) is an efficient ceramic material suitable for electric furnaces and high temperature applications, including metal heat treatment, ceramic production, glass production and semiconductor manufacturing. SiC is utilized across a wide variety of industries such as metal heat treatment, ceramic manufacturing and semiconductor fabrication.

These elements feature hot zones made of recrystallized SiC that have been specially optimized to resist oxidation and common process gases, making them suitable for demanding settings with cyclical heating needs. Rod or multi-leg designs are available, making these elements suitable for demanding situations with heating demands that vary over time.

As with other heating elements, SiC heating elements exhibit resistance that varies with temperature and time, which may present issues if power supplies to them aren’t managed appropriately. To mitigate this potential problem, it is vital that a voltage regulating equipment with an ample regulating range be utilized; this way, you can be certain that their output won’t go beyond its rated power and thus protect and extend their lifespan.

DM Type

Silicon carbide is an extremely hard crystalline compound of silicon and carbon that occurs naturally in rare minerals such as moissanite, corundum or kimberlite; or manufactured synthetically. With its high Mohs hardness rating and superior thermal conductivity characteristics – as well as a low expansion rate and resistance to chemical reactions – silicon carbide makes an ideal heating element in furnaces as it won’t damage materials being heated in the process.

DM type hollow tubular heaters feature thickened ends to facilitate precise temperature control and enhanced durability under thermal stress, making it suitable for ceramic kilns, glass production facilities, metal heat treatment processes and electronic materials processing furnaces.

Silicon carbide electric heaters have the capacity to withstand higher temperatures than their metal counterparts and boast longer lives due to their superior resistance against corrosion caused by water vapor, nitrogen oxides, hydrogen chloride gas emissions, alkaline gases or metal oxides.

SCR Type

The SCR Type silicon carbide heating element is a rod-shaped non-metallic thermal device designed for industrial use. Featuring a hot zone constructed of recrystallized silicon carbide which has been optimized to resist common process gases while remaining corrosion and chemical stability-friendly at lower temperatures, this heating element can be found in various industries.

This element is constructed of high-density reaction bonded silicon carbide and comes in various shapes, lengths, and electrical connections to suit different requirements. It has the capacity to withstand heavy current loads as well as rapid heating/cooling cycles as well as thermal shocks without losing performance or reliability.

Silicon carbide heaters are an extremely useful and versatile tool in industrial settings, offering exceptional thermal efficiency, low thermal expansion rates, extreme hardness and corrosion-resistance properties. SC, H, DM and SCR types of silicon carbide heaters can help achieve uniform heat distribution throughout large furnaces while simultaneously controlling precise temperatures during high-tech manufacturing applications.

GC Type

Silicon carbide heating elements offer several advantages over metal elements: corrosion and oxidation resistance; greater power output at higher watt loads; long lifespan when exposed to extreme temperatures or power requirements.

Silicon Carbide (SC) is an inert and hard ceramic material, known for its resilience against sudden temperature changes. These properties make SC an excellent material choice for electric furnaces, with its high melting point and resistance to chemical reactions making it suitable for heat-treating equipment as well.

GC type silicon carbide rods are versatile tools designed for torch furnaces. Available in various sizes and materials, these rods can also be shaped into various forms to meet specific industrial requirements. Based on your application needs you may select from among several varieties of these silicon carbide rods:
