Pressureless Sintered Silicon Carbide (SSiC) kiln furniture is an advanced ceramic material known for its exceptional properties. These products are widely used in industries requiring high-performance materials capable of withstanding extreme conditions.
Material Characteristics
Sintered silicon carbide (SSiC) is a polycrystalline alpha-type silicon carbide produced from pure submicron SiC powder with non-oxide sintering aids. It is processed in a proper ceramic forming process of extrusion, dry pressing or isostatic pressing, and sintered at 2,200℃ in an inert gas atmosphere.
Advantages of SSiC products
1. High Mechanical Strength: SSiC products exhibit superior mechanical strength and hardness, outperforming most traditional ceramic materials. The bending strength is 4 times that of RSiC, 2 times that of NSiC, and 50% higher than SiSiC.
2. Excellent Thermal Shock Resistance: due to the excellent thermal conductivity, consistently low thermal expansion coefficient and minimizing internal temperature gradient, it has excellent thermal shock resistance and can be more adaptable to rapid heat cycling than other materials.
3. Super High-Temperature Resistance: They maintain structural integrity at high temperatures, making them ideal for use in kiln furniture up to 1700℃ even under load.
4. Superior Oxidation Resistance: SSiC is highly resistant to chemical corrosion, even in harsh acidic or alkaline environments.
5. Wear Resistance: Their exceptional wear resistance ensures a long service life, reducing the need for frequent replacements.
6. Lightweight: Compared to other ceramic materials, SSiC kiln plates are significantly lighter, which helps improve energy efficiency in various industrial processes.
Take the kiln plates for loading the same weight in the same condition for example, the thickness of SSiC plate is 2-3mm, while OSiC plate is 8-10mm, SiSiC/ NSiC/ RSiC is 5-6mm, cordierite-mullite should be 12-15mm.
Comparison with Other Silicon Carbide Materials
Applications
SSiC kiln furniture is extensively used in:
Ceramic Industry: As part of kiln furniture for firing ceramics, reducing energy consumption and improving firing efficiency.
Metallurgical Industry: For lining and supporting structures in high-temperature furnaces.
Chemical Industry: In corrosive environments where other materials would quickly degrade.
Aerospace Industry: For components that require high strength and temperature resistance
Conclusion
SSiC kiln plates offer a combination of properties that make them indispensable in high-performance industrial applications. Their advantages over other types of silicon carbide materials ensure they remain a preferred choice for industries that demand the best in terms of durability, efficiency, and reliability.
