Silicon Carbide bricks are among the most trusted and versatile refractory materials to withstand demanding industrial environments, and are used widely throughout steelmaking equipment such as electric arc furnaces and ladles, waste-to-energy plants for lining furnaces and incinerators, and waste management plants for lining furnaces and incinerators.
SiC refractory bricks feature an exceptional composition that makes them extremely resistant to chemical corrosion from acids and alkalis, as well as environmental elements like humidity. Manufacturers create these green bricks through mixing, shaping, drying and pre-firing processes and are reliable for high temperature applications.
High Temperature Resistance
SiC bricks stand out among other refractory materials by being exceptionally heat resistant, as well as withstanding constant mechanical stress in industrial environments without losing their structural integrity. As a result, these bricks make an excellent choice for lining furnaces or kilns dealing with high levels of heat or harsh chemicals and liquid metals.
One such application of Corundum Silicon Carbide brick in blast furnace linings is its use as a blast furnace lining. Constructed from brown corundum aggregate and phosphoric acid as binder, its bricks are dried before firing at very high temperatures to produce excellent thermal stability, oxidation resistance, impact resistance, strong strength, volume stability and low coefficient of expansion properties – widely utilized across non-ferrous aluminum smelting stills, zinc vertical cans, steel smelter linings as well as ceramic kiln frame plates/pillars/pillars/divider flame plates/garbage incinerator linings etc – among many wear-resistant applications.
Excellent Corrosion Resistance
Silicon carbide bricks feature excellent resistance to chemical corrosion, making them the perfect choice for environments involving harsh chemicals or molten metals. Even with constant exposure to such corrosive substances, their structural integrity remains intact, lengthening furnace and kiln lifespans while decreasing maintenance or replacement needs.
Clay-bonded silicon carbide brick uses black SiC as its raw material and soft clay binder to produce a material with excellent thermal conductivity, strong acid slag resistance, and high strength – qualities which made this one of the first types of silicon carbide firebrick ever developed. Widely utilized as ceramic kiln furniture (shed, bracket, raft), as well as muffle furnace lining brick.
Oxidation-bonded silicon carbide brick is manufactured using SiC and Si powder as raw materials, and sintered using oxidation for sintered manufacture. With low thermal expansion coefficient and strong mechanical strength properties, it is widely used in aluminum industry (aluminum electrolyzer lining and zinc powder furnace lining) as well as nonferrous metals industry (refiner furnace lining). Furthermore, this brick offers excellent resistance to erosion, alkali corrosion, and sulfur corrosion – perfect for use as refiner furnace lining).
High Strength
Silicon Carbide Brick (SCB) boasts exceptional strength that allows it to withstand high temperatures and harsh chemical environments commonly found in industrial applications, making it an invaluable component in many high-stakes processes such as petrochemical production and aerospace technology.
Not only is this refractory material exceptional mechanically, it offers exceptional thermal conductivity and chemical corrosion resistance as well as helping prevent thermal stress cracking ensuring equipment can operate safely in demanding conditions.
Clay bonded SiC brick is one of the earliest developed forms of silicon carbide refractories, combining silicon carbide with a clay binder to achieve an ideal combination of durability, thermal conductivity and corrosion resistance.
Reaction bonded SiC bricks are produced through a reaction sintering process using industrial silicon carbide grains as the main raw material and in situ-nitridated b-SiC as secondary raw material. These silicon carbide refractory bricks feature excellent alkali corrosion resistance and low water vapor oxidation erosion rates while boasting compact structures, high temperature volume stability and superior flexural strength compared to similar bricks on the market.
Low Thermal Expansion
Silicon carbide bricks feature remarkable thermal stability that helps them resist deformation while remaining structurally sound, even under high-temperature environments such as kilns or furnaces.
Bricks are formed using industrial silicon carbide particles bonded together using clay or silicon nitride through a reaction sintering process in special kilns, where temperature and duration of this firing process is carefully managed in order to achieve the desired physical and chemical properties of the refractory material.
Refractory bricks must then be dried to remove excess moisture and prevent cracking or damage during their subsequent firing process. They are ideal for various applications, including ceramic kilns (sheds, nozzles and plugs), non-ferrous metal smelting furnaces, waste incineration furnaces and waste incineration furnace liners as well as aluminum refining furnace linings. They also boast impressive resistance to erosion and corrosion and boast an incredible Mohs hardness rating of 9; making them one of the hardest non metal alloy materials out there!
