Silicon carbide is a hard, chemically inert ceramic that is capable of withstanding high temperatures and thermal shock, making it an excellent choice for nonferrous metal smelting applications such as aluminum electrolytic tank linings, copper melting furnace linings, slag bricks and blast furnace tuyere water-cooled tubes.
SIC can also be used as an additive to enhance refractory castables’ slag resistance and thermal shock resistance, so this article will highlight its benefits as an application tool.
Resistance to Corrosion
Silicon carbide refractories provide superior corrosion protection, making them perfect for use in furnace linings, kilns and other high-temperature applications. Furthermore, they offer excellent slag resistance and thermal shock resistance properties.
Silicon Carbide Refractories have many applications in non-ferrous metal smelting, steel production, and waste-to-energy power plants. Their properties include corrosion and impact resistance as well as thermal conductivity for indirect heating materials.
Refractory castables are composed of silicon carbide aggregates in various sizes embedded within an oxide binder matrix containing fine powders. Their quality depends on their ability to withstand the aggressive environment present during municipal waste incinerator operation; high temperature, mechanical wear and chemical erosion all influence its lifespan.
Microstructural analysis revealed the corrosion behavior of commercial sidewall silicon nitride bonded silica refractories (SNBSCs) in an aluminum reduction cell environment was investigated. Porosity levels, binder content, and the ratio between a/b Si3N4s were all influential on corrosion rates for SNBSCs; specifically due to increased chemical reactivity due to their larger surface areas than a/b Si3N4 binder phases allowing more chemical reaction with unreacted metallic silicon present within these crystals that caused its corrosion mechanism within aluminum reduction cell environments.
High Temperature Resistance
There are various kinds of refractory materials. When selecting one for your application, it is essential to take into account factors like temperature range, chemical environment and other requirements. Silicon carbide (SiC) has high temperature resistance making it an excellent choice for industrial settings as well as applications requiring thermal shock resistance and chemical resistance.
