Silicon Carbide heating elements are made from high purity alpha silicon carbide grains, that are extruded in the form of rods or tubes, before being bonded together by a process of recrystallization, at temperatures of over 2500°C (4530°F). The firing process ensures the creation of rods with strong uniform bonds between adjacent grains, and the particle size distribution is closely controlled to ensure optimum density and resistance to the process atmosphere.
Silcarb SiC elements have the conventional central hot zone and two low resistivity cold ends. Three pieces Alpha Silicon Carbide Rod features welded low resistance cold ends which run cooler than anyone-piece cold ends and are joined to the hot zone using the strong reaction-bonding technique. As the resistivity of the hot zone material is considerably higher than that of the cold ends, most of the heat is generated in the hot zone, when power is applied. The cold ends, which pass through the furnace lining, remain relatively cool and are sprayed over a short length at the end with aluminum, to form a low resistance contact for the aluminum terminal braids. Heat is concentrated in the Furnace, not the ends, for energy efficiency.
Silcarb manufactures high-end Silicon Nitride products for foundry applications.
We buy high-quality Silicon Nitride powders form the best possible sources. Silicon nitride is almost as light as silicon carbide (SiC). It has high wear resistance along with high temperature and high corrosion resistance at low specific weight. The presence of micro-structure gives them exceptional thermal shock resistance and their high fracture toughness makes them resistant to impact and shocks. This high strength is a result of the high energy and covalent bonding structure of the material which maintains its strength even at high temperatures. Silicon nitride exhibits excellent tribological properties and is also used in wear applications. This makes Silicon nitride suitable for high temperature applications.
The silicon nitride powder is mixed with oxidic sinter additives. They are then processed with normal ceramic shaping methods and are sintered at 1800 to 1900°C. All of this happens in a nitrogen atmosphere and at pressures of up to 100 bar. We ourselves have an in-house spray dryer/ freeze drier where we prepare our powders with binders etc. varying component shapes can be made using normal ceramic shaping method. All Silicon Nitride products that silcarb manufactures are isostatically pressed. These are then dried and fired in our state-of-the-art sintering furnaces to temperatures of 1800°C. We manufacture Thermocouple Tubes, Immersion Heater Tubes for Molten Aluminium as well as Molten Zinc and Molten Copper, Low-Pressure Stalk Tubes (LPDC Stalk tubes), Riser tubes, Dosing tubes degassing rotors, Molten metal transfer cups, launders etc.
In order to achieve very tight tolerances, fully sintered material must be machined with diamond tools. This processing of the sintered components requires a very precise diamond coated tool to obtain the desired shape.
The silicon nitride ceramics are available in different product forms and can be customized to different standard sizes and geometries to suit a variety of application. Contact us for any further details.
