Silicon Carbide Seals Mechanical Seal Pumping Ring Silicon Carbide Rings
Silicon carbide ceramics are much lighter and harder than other ceramics and are resistant to acids and lyes.
Pressureless sintering techniques make it possible to manufacture dense compacts of silicon carbide, making it a widespread structural material. These ceramics are lightweight because silicon carbide consists primarily of lightweight elements. They also have low thermal expansion and high conductivity and are exceptionally chemically stable.
They are used for fixed and moving turbine components, suction box covers, seals, bearings, ball valve parts, and heat exchangers.
