Silicon Carbide Plate

Oxide-bonded silicon carbide plates are high-performance ceramic plates made by sintering at high temperatures with silicon carbide (SiC) as the main aggregate (content usually ≥ 80%) and an oxide binder.

The production process typically involves raw material mixing, forming (such as isostatic pressing or molding), and high-temperature sintering (1300-1600℃). Some products require the addition of anti-oxidation agents or expansion agents to optimize performance.

What Types of Silicon Carbide Plates Are There?

Highland Refractory classifies Silicon Carbide Plates by production process and performance to meet diverse industrial needs, including Reaction-Bonded Silicon Carbide Plates (with high density and excellent thermal conductivity, suitable for high-wear environments like kiln shelves) and Sintered Silicon Carbide Plates (featuring ultra-high temperature resistance up to 1600℃, ideal for extreme-heat equipment such as metal smelting crucibles); each type of Silicon Carbide Plate is optimized for specific scenarios, ensuring compatibility with both low-temperature thermal processing and high-temperature industrial operations.

Advantages of Silicon Carbide Plates

Highland’s Silicon Carbide Plate stands out in harsh industrial environments with core strengths: it boasts exceptional wear resistance (5–10 times higher than ordinary refractory materials), ensuring long service life in high-abrasion zones; it has excellent thermal conductivity, enabling uniform heat transfer and reducing energy consumption in heating equipment; it also resists corrosion from acidic and alkaline slags, maintaining structural integrity even in chemically aggressive settings—these advantages make the Silicon Carbide Plate a reliable choice for demanding high-temperature and high-wear applications.

Applications of Silicon Carbide Plates in Different Industries

Silicon Carbide Plates are widely used across key industrial sectors due to their versatile performance: in the ceramic and glass industry, they serve as kiln shelves and roller surfaces, withstanding repeated heating cycles and preventing product adhesion; in the metal processing industry, they act as heat exchanger components, leveraging high thermal conductivity to improve cooling efficiency; in the chemical industry, they line reaction vessels to resist corrosive media—each application highlights the Silicon Carbide Plate’s ability to adapt to diverse harsh conditions, supporting stable production processes.

Difference Between Silicon Carbide Plates and High Alumina Bricks

Silicon Carbide Plates (Highland) excel in high-wear and high-thermal-conductivity scenarios—they offer superior wear resistance for long-term use in abrasive environments, excellent thermal conductivity for efficient heat transfer, and broad corrosion resistance to acidic/alkaline media, making them ideal for kiln shelves and heat exchangers; High Alumina Bricks, by contrast, focus on high-temperature structural stability, with strong load-bearing capacity at ultra-high temperatures (up to 1700℃) and good thermal shock resistance, suiting furnace linings and high-temperature structural parts—each product targets distinct industrial needs, with the Silicon Carbide Plate leading in wear and heat transfer performance.
