Silicon Carbide Plate Overview

ACM supplies silicon carbide plates, also known as SiC plates, in sintered, reaction-bonded, and recrystallized grades. Available sizes reach up to 200 × 200 mm, with thicknesses from 1 to 20 mm. Depending on the grade, these plates provide working temperatures up to 1650°C, flexural strength up to 400 MPa, and thermal conductivity up to 110 W/m·K. Custom sizes and machining are available upon request.

Applications of Silicon Carbide Plates

Our sintered SiC plates are suitable for a wide range of high-temperature and wear-resistant applications:

• Iron and Steel Smelting — Withstands up to 1550°C with high thermal shock resistance, reducing downtime from thermal cycling failures.
• Kiln Shelves and Furniture — Resists thermal shock and erosion, maintaining flatness over multiple firing cycles and extending service life.
• Feeding Systems — Handles abrasive materials with high wear resistance, reducing system wear and lowering maintenance costs.
• Spray Nozzles and Shot Blast Nozzles — Dense structure (low porosity) provides chemical resistance and extends nozzle life in abrasive media applications.

Why Silicon Carbide vs Alumina or Zirconia?

• Higher thermal conductivity (110 W/m·K vs 25-30 W/m·K for alumina) — faster heat dissipation, cooler operation
• Higher hardness — better wear resistance in abrasive environments
• Lower thermal expansion — better thermal shock resistance
• Lower density than tungsten carbide — lighter weight for armor and structural components

Product Variants

Advanced Ceramic Materials (ACM) offers a range of silicon carbide plates, including:

• Sintered Silicon Carbide Plates: Known for their high mechanical strength and thermal stability.
• Reaction-Bonded SiC Plates: Combining the benefits of high strength with versatile applications.
• Recrystallized SiC Plates: Featuring exceptional purity and excellent thermal properties.

Choose the right SiC grade for your application:

Recrystallized grades prioritize purity (99.5%) over mechanical strength, making them suitable for high-temperature applications where contamination is a concern.
