Excellent oxidation and corrosion resistance Silicon Carbide Beam
1. Product Description
Silicon carbide beams can be used for a long term without fracture
or bend because of their advantages of high temperature tolerance,
high flexural strength, good oxidation resistance and wear
resistance. So the products are widely applicable in roller kilns
for domestic ceramics, health ceramics, building ceramics, magnetic
materials.
They have higher bearing strength, high temperature tolerance,
corrosion resistance, wear resistance, and there are no deformation
even under very high temperature. The rollers display more than 10
times operational life compared to Alumina Rollers.
Reaction-sintered, silicon-infiltrated silicon carbide (SiSiC)
components are produced by slip-casting or extruding a mixture of
silicon carbide, carbonaceous material and other ingredients into
the desired shape. The resulting green body is then fired in the
presence of a high concentration of silicon metal. As the silicon
diffuses through the body, it reacts with the carbonaceous material
to form additional silicon carbide, sintering the silicon carbide
structure and increasing the density. The remaining open porosity
is then filled with the excess silicon. SiSiC has a MOR
approximately 40% higher than NSiC and twice that of ReSiC. Its
high strength and oxidation resistance make SiSiC the material of
choice for most applications where the maximum temperature is below
its 1350°C use limit.
Sintered-alpha silicon carbide (SSiC) components are manufactured
by pressureless-sintering a shape produced by slip casting,
extruding, or pressing submicron alpha-silicon carbide powder. SSiC
has the highest MOR, best oxidation resistance and highest use
temperature (1750°C) of the four materials under discussion. SSiC
is also the most expensive of the four materials and is generally
economically viable only as an alternative to ReSiC at temperatures
above the 1450°C use limit of NSiC.
Characteristics:
Max temperature tolerance 1380 degree
Excellent oxidation and corrosion resistance
High thermal conductivity and shock resistance
High mechanical strength and abrasion resistance
