| Silicon Carbide (SiC) |
SiC ceramics are very hard and strong non-oxide materials that
possess unique thermal, mechanical and electronic properties. They
are very hard, second only to diamonds, with excellent wear and
abrasion resistance. They can maintain high mechanical strength at
high temperature. The most impressive is their high thermal shock
resistance. They can be quenched in water from 1200°C without
cracking. The ceramics also have high chemical corrosion resistance.
Silicon Carbide (SiC) ceramics have wide applications in the fields of
ceramics, glass ceramics, industrial kilns, automobiles, metallurgy,
petroleum, chemical, steel, machinery, electric power, aerospace, etc.
Unique key characteristics of SiC
Skyline components can provide SiC products based on the
requirements of customers. The materials include Oxide bonded,
Nitride bonded, Recrystalized, Reaction bonded, and Sintered SiCs.
Our SiC products include: roller, square cross
beam, burner nozzle sets, combustion chamber,
heat radiation ceramic inner tube, cooling air pipe,
desulphurization nozzle, sealing parts, and impeller.
Oxide Bonded SiC (OBSiC)
OBSiC has a maximum service temperature of 1500°C. It has good
thermal shock, corrosion resistance and excellent thermal conductivity.
It can be used in oxygen atmosphere furnaces and molten non-ferrous
metals such as Aluminum. It is resistant to oxidation and slag attack.
OBSiC doesn’t conduct electricity. It is about 15% porous and not gas
tight.
Nitride Bonded SiC (NBSiC)
NBSiC has the similar characteristics as OBSiC. But it is denser, less
porous (10%), and has slightly better thermal shock, corrosion
resistance, and twice the crushing strength of OBSiC. It has a
maximum service temperature of 1450°C.
Recrystallized SiC (ReSiC)
ReSiC is pure silicon carbide material. It has a porosity of about 17%,
so is lightweight and can be fabricate to very complex shapes. It can
operate in temperature of 1650°C (oxidizing) and approximately 2000°C
(under protective atmosphere).
Reaction Bonded SiC (RBSiC or SiSiC)
RBSiC or SiSiC has high strength, high thermal conductivity, and low
porosity (<0.1%). It is gas tight, and can conduct electricity. It is highly
resistant to oxidation, impacting of rapid cooling or heating, and
shaking. No oxidation and bending deformation occur at high
temperature for long-term use.
Sintered Alpha SiC (SSiC)
SSiC has a maximum service temperature of 1700°C in both oxidizing
and corrosive atmospheres. It can be used in chemicals including
strong acids and bases. It is chemically inert. It has five times the
thermal conductivity, and ten times thermal shock resistance of
Alumina ceramics.
