    Extreme environmental resilience

    Resistant to strong acids, strong alkalis, oxidants, and organic solvent corrosion, applicable to a full pH range of 0-14; chemically inert, superior to stainless steel/alloys, preventing ion leaching and contamination of ultra-pure fluids. Capable of long-term working temperatures exceeding 1600°C, with excellent thermal shock stability and pressure resistance greater than 100 MPa, suitable for supercritical fluids and high-pressure steam systems.

    Reliability of Mechanics and Thermodynamics

    Compressive strength is greater than 3500 MPa, with no risk of plastic deformation. It has a low coefficient of thermal expansion compatible with most metal housings, preventing seal failure caused by thermal cycling. Additionally, its high thermal conductivity quickly dissipates localized frictional heat, preventing thermal stress-induced cracking.

    Outstanding tribological performance

    With an ultra-low abrasion rate, the hardness of the SiC-SiC friction pair exceeds 2500 HV. Its self-lubricating properties significantly reduce adhesive wear, providing a lifespan over five times that of aluminum oxide ceramic valves. It is resistant to wear from particle erosion and can withstand media containing solid particles (such as slurry and catalysts), with a surface erosion rate of less than 0.01 mm per year.

    Frequently Asked Questions (FAQ)

    Q: What is the chemical compatibility of this material?

    It is highly resistant to strong acids, strong alkalis, oxidants, and organic solvent corrosion across a full pH range of 0 to 14. Being chemically inert, it outperforms stainless steel and alloys by preventing ion leaching and contamination in ultra-pure fluid systems.

    Q: What are the maximum temperature and pressure limits it can withstand?

    The material is capable of long-term operation at temperatures exceeding 1600°C. It exhibits excellent thermal shock stability and can withstand pressure levels greater than 100 MPa, making it suitable for supercritical fluids and high-pressure steam systems.

    Q: How does the material prevent seal failures during thermal cycling?

    It features a low coefficient of thermal expansion that is highly compatible with most metal housings, which prevents seal failure caused by thermal cycling. Additionally, its high thermal conductivity rapidly dissipates localized frictional heat to prevent thermal stress-induced cracking.

    Q: What makes the mechanical structure highly reliable?

    It has an exceptional compressive strength of greater than 3500 MPa, which completely eliminates the risk of plastic deformation under extreme load conditions.

    Q: How does the wear resistance compare to standard ceramic valves?

    The hardness of the SiC-SiC friction pair exceeds 2500 HV, and its self-lubricating properties significantly reduce adhesive wear. This provides a operational lifespan that is over five times longer than standard aluminum oxide ceramic valves.

    Q: Can this material handle media containing abrasive solid particles?

    Yes. It is highly resistant to particle erosion and can withstand abrasive media such as slurry and catalysts, maintaining an extremely low surface erosion rate of less than 0.01 mm per year.
