Silicon Carbide Refractory Materials

실리콘 카바이드 내화 재료

Silicon carbide refractory materials are high-grade refractory products made of silicon carbide (SiC) as raw material and main crystalline phase. They possess multiple superior performances: high thermal conductivity and low thermal expansion coefficient, delivering excellent thermal shock resistance and anti-cracking capability under drastic temperature changes; great strength at normal and high temperatures with superior wear resistance; stable chemical properties to resist most acid, alkali and slag corrosion.

제품 정보

As silicon carbide refractories are non-plastic, a binder is required to form a solid product, making the binder’s properties and bonding form critical to product performance. Based on the bonding phase, they are mainly classified into oxide-bonded, nitride-bonded, and self-bonded/recrystallized types. These refractories are widely used in iron and steel metallurgy (e.g., blast furnace belly and tuyere linings), non-ferrous metallurgy (e.g., vertical zinc retorts and aluminum cells), environmental protection and chemical industries (e.g., waste incinerators, wear- and corrosion-resistant pipes), as well as ceramic and electronic industries (e.g., kiln furniture, thermocouple protection tubes). Current development focuses on compositing, functionalization, and refinement to meet customized requirements under extreme operating conditions.
