Silicon carbide Cyclone
Reaction bonded silicon carbide is a multi-phased material typically containing 7-15% silicon metal, some minor amount of unreacted carbon, with the remaining body being SiC. Reaction bonded SiC materials are manufactured utilizing a variety of processes depending on desired final product geometry, configuration, and required tolerances.
Reaction bonded silicon carbide has proven to be an excellent material choice for wear applications such as pipe liners, flow control chokes and larger wear components in the mining as well as other industries. CALSIC RB offers an economical and reliable material option for many applications where the corrosion resistance or wear resistance of CALSIC S (sintered silicon carbide) is not necessary.
Typical properties of silicon carbide are:
Excellent thermal shock resistance
Excellent hot strength
Excellent abrasion resistance
Good thermal conductivity
Relatively low coefficient of thermal expansion
Typical applications for silicon carbide are:
Kiln furniture for powder metal and ceramic processing
Kiln components including:
hearths
entrance tiles
skid rails
muffles
side walls
arches
