Silicon Carbide Ceramic Valve Seats & Cores - High-Quality China Suppliers & Factory for Reliable Performance
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.
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.
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.
