Silicon Carbide (SiC) bricks are high-performance refractory materials commonly utilized in industrial applications that present challenging environments. These bricks are known for their exceptional durability and resistance to heat, chemical attack and abrasion.
These properties make ceramic linings perfect for furnaces and kilns, where they must endure constant exposure to molten metals and harsh chemicals. Furthermore, ceramic materials offer low thermal expansion rates that minimize dimensional changes over time.
Superior Thermal Conductivity
Silicon carbide bricks provide superior thermal conductivity to enable efficient operation at high temperatures, spreading heat across their applications evenly and decreasing energy consumption.
These bricks feature a strong structure that enables them to withstand physical stress and pressure without cracking or deforming, helping extend equipment lifespan and overall operational efficiency.
Production of these refractory bricks begins with careful selection of raw materials. From there, manufacturing involves mixing, shaping, drying, pre-firing and high temperature firing processes that create green bricks. At each step in this process, manufacturers employ stringent quality control measures to ensure that these green bricks meet specifications while providing optimal performance in challenging environments.
High-Temperature Resistance
Silicon carbide bricks maintain their strength at elevated temperatures up to 1600 degC, providing essential protection for equipment and machinery in environments characterized by extreme temperatures and chemical exposure. As such, these bricks enhance efficiency and extend lifespan in applications from steel production and metallurgy production to ceramics production and glass production.
Chemical resistance is another distinguishing characteristic of these bricks, providing exceptional resistance against acids, alkalis and molten salt attacks. This makes them suitable for applications in the petrochemical industry such as non-ferrous metal smelting, oil refining and synthesizing industrial chemicals.
Although premium refractory materials offer unmatched durability, they tend to command higher prices than traditional fireclay bricks. AGRM ensures competitive pricing by taking advantage of efficient production techniques and adhering to stringent quality control standards to provide customers with maximum value for their dollar spent.
High-Strength Properties
Silicon carbide bricks’ superior strength properties make them the ideal choice for areas that experience intense physical strain, such as furnace floors or walls where molten metal or abrasive raw materials move freely. Furthermore, their excellent abrasion resistance helps prevent cracking that could hinder performance and performance issues that impact performance.
Silicon carbide bricks feature low thermal expansion rates, meaning that when temperature fluctuations occur they expand and contract very little; helping reduce heat loss and energy use as well as providing greater flexibility for refractory lining applications.

Abrasion Resistance
Silicon carbide bricks possess one of the highest hardness levels among all refractory materials, even surpassing diamond. Their superior strength enables abrasion resistance which protects structures against heavy loads and stresses.
Corundum silicon carbide refractory bricks are widely used in steelmaking as blast furnace bodies, tuyere combination bricks and slag joint bricks as well as ladles, tundishes, aluminum refining furnace kiln linings and zinc distillation tanks linings linings; ladles; tundishes, aluminum refining furnace kiln linings as well as support materials in high temperature kilns for ceramic fusing and glass casting purposes.
Silicon Carbide Refractory Bricks have exceptional erosion resistance against acidic slag and solvent erosion in environments with alkali attacks, providing stable operation without build-ups that impede performance. These features ensure stable operation without impeding performance.
Chemical Resistance
Silicon carbide bricks offer excellent corrosion protection in environments where corrosion could otherwise damage equipment, extending refractory lining lifespan and decreasing replacement needs. Their chemical-resistance is especially advantageous when used as protective covering for equipment in furnaces or boilers that uses hot molten metals or chemicals such as ammonia. Silicon carbide bricks also protect refractory linings from damage or wear, further prolonging their service life and decreasing replacement needs.
These materials also possess low thermal expansion properties, making them suitable for applications requiring dimensional stability. Their low expansion rates help prevent thermal stress from developing as temperature fluctuates and ensure optimal performance even in high temperature environments.
Silicon carbide carbon bricks are essential components in steel manufacturing, glass production and ceramic production due to their incredible durability. Able to withstand mechanical stress, abrasion and extreme temperatures without compromise to structural integrity – silicon carbide carbon bricks extend equipment lifespan in demanding industrial environments while increasing operational efficiency.
