Nozzles, burners and radiant tubes in different materials of silicon carbide (SiC, SiSiC, RSiC) are used for direct fired furnaces (combustion) or indirect (convection or radiation). Thermocouple protection and custom made parts with special resistance to thermal impact.
We offer the entire range of products (rods, rollers, supports, etc.) for electric or gas furnaces.
Until the invention of boron carbide in 1929, silicon carbide was the hardest synthetic material known. It has a Mohs hardness rating of 9, approaching that of diamond. In addition to hardness, silicon carbide crystals have fracture characteristics that make them extremely useful in abrasive wheels and abrasive paper and cloth products. Its high thermal conductivity, along with its resistance to high temperatures, low thermal expansion, and resistance to chemical reaction, makes silicon carbide valuable in the manufacture of high-temperature bricks and other refractories. It is also classified as a semiconductor, which has an electrical conductivity between that of metals and insulating materials. This property, in combination with its thermal properties, makes SiC a promising replacement for traditional semiconductors such as silicon in high-temperature applications.
