Silicon Carbide Refractory Materials

炭化ケイ素耐火物

炭化ケイ素耐火物は、炭化ケイ素（SiC）を原料と主結晶相とする高級耐火物です。熱伝導率が高く、熱膨張率が低いため、急激な温度変化に対して優れた耐熱衝撃性と耐クラック性を発揮します。.

製品情報

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.
