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.
