Silicon carbide, an exceptionally durable refractory material, makes an excellent choice for Silicon Carbide Nozzle in industrial combustion processes and shot blasting applications. Acheson first utilized this material as an industrial abrasive, before eventually adopting it for use in refractory products such as thermal couple protectors and saggers; industrial kiln lining; and gas turbine liners.
High-Temperature Resistance
Silicon carbide is an extremely tough material capable of withstanding high temperatures, making it an excellent choice for use in industrial furnaces, kilns, and certain boilers that generate large amounts of heat. Reaction-bonded silicon carbide has an extremely low coefficient of thermal expansion – meaning it won’t expand or contract significantly depending on changes in temperature.
Reaction bonded silicon carbide is created through the reaction between porous carbon or graphite and molten silicon, producing a ceramic with excellent refractory and chemical properties. Available in numerous shapes and sizes, reaction bonded silicon carbide makes an ideal material for applications requiring highly durable ceramic materials; its thermal shock resistance makes it a suitable option for industrial furnace nozzles and equipment.
Reaction bonded silicon carbide’s thermal shock resistance and oxidation resistance make it the ideal material for industrial furnaces that must withstand extreme temperatures. Furthermore, its corrosion-proof qualities also make it suitable for many different uses – making this material safe to work with!
Reaction bonded silicon carbide has become an indispensable material in power, steel, ceramics, high temperature furnaces, mining, coal, alumina, petroleum processing plants and the mechanical manufacturing industries globally. Reaction bonded silicon carbide can be formed into Silicon Carbide Nozzle, linings and larger wear components suitable for mining processes as well as desulfurization processes.
Thermal Conductivity
Silicon carbide boasts an exceptionally high thermal conductivity that allows it to quickly transfer heat, providing it with excellent resistance against oxidation, corrosion and wear caused by exposure to corrosive substances. Furthermore, its extremely low coefficient of expansion enables it to withstand rapid temperature changes without degrading or cracking under strain.
Reaction bonded silicon carbide is produced by infiltrating molten silicon into a porous carbon or graphite preform, where it reacts to form silicon carbide. Though less strong and harder than sintered silicon carbide, this material may be preferable due to lower costs for production as well as its excellent wear resistance, dimensional stability, wear resistance properties and ability to be formed into various shapes and sizes.
This material is frequently utilized to craft wear components for industrial equipment, including pumps, mechanical seals and bearings as well as larger wear components found on kilns, rotary, tunnel and shuttle furnaces, metallurgy equipment as well as larger wear components used in grit blasting nozzles and abrasion-resistant linings for kilns, crucibles and furnaces.
Abrasion Resistance
Silicon carbide (carborundum) is a tough ceramic material with outstanding corrosion and abrasion resistance, used widely in metalworking and refractories industries as heating devices or wear components requiring resistance against high temperatures and pressures. Contrasting with diamond’s very hard yet low thermal conductivity characteristics, silicon carbide has a higher melting point, lower coefficient of expansion rate and great durability compared to diamond.
Reaction bonding is a manufacturing method for silicon carbide that involves mixing a-SiC powder with graphite powder and additives, before sintering at 1600 in a vacuum heating furnace to form b-SiC which can then be cut into various shapes and sizes to form ceramic products. Reaction sintered SiC has excellent resistance against abrasion, oxidation and heat and is widely used in industrial furnaces and burners.
Reaction Bonded Silicon Carbide (RBSiC or SiSiC) products that we manufacture include ceramic rollers, burner nozzles, desulfurization nozzles, saggers, crucibles, radiation pipes, thermocouple protection pipes, cooling tubes, plate, sealing beams and special-shaped parts. Our reaction sintering silicon carbide kiln flame furniture is used in household porcelain kilns (roller kiln, tunnel kiln, shuttle kiln). Reaction bonded silicon carbide ceramic sandblastingspit linings bushings tube fittings are used by domestic and foreign mineral processing companies alike.
Chemical Inertness
Reaction Bonded Silicon Carbide is an extremely durable material with outstanding resistance against abrasion, impact, thermal shock, corrosion and other harsh operating conditions. Furthermore, its low coefficient of thermal expansion makes it suitable for applications which demand high temperatures and pressures.
chemical inertness of Silicon Carbide Nozzle makes them especially advantageous when handling acids and caustics that could otherwise erode other nozzle materials. Their wide array of shapes and designs makes them suitable for almost every machinery application.
RBSIC, its flexural strength increases while elastic modulus decreases due to free silicon formation. Reaction Bonded SIC has found widespread application in bulletproof armor sheets, mechanical bearings, kiln furniture, Silicon Carbide Nozzle and sealing rings in industries including electric power generation, ceramics manufacturing, metallurgy iron steel mine coal alumina petroleum chemical wet desulfurization machinery manufacturing worldwide.
