Our Advantages

• High Hardness: SiC is one of the hardest materials known to man, making it ideal for use in applications that require a high degree of hardness and abrasion resistance.
• High Thermal Conductivity: SiC has a high thermal conductivity, making it ideal for use in high-temperature applications such as furnace linings and refractories.
• High Chemical Stability: SiC is highly resistant to chemical corrosion, making it suitable for use in harsh chemical environments.
• Low Thermal Expansion: SiC has a low coefficient of thermal expansion, which means it does not expand or contract significantly with changes in temperature, making it ideal for use in applications that require dimensional stability.
• Wide Bandgap: SiC has a wide bandgap, which makes it suitable for use in high-power electronic devices such as power diodes, thyristors, and transistors.
• High Strength: SiC has high strength and stiffness, making it suitable for use in applications that require a material that can withstand high stresses.
