Sanitary Ceramics Rollers Sisic Rollers For Lithium battery positive anode application temperature 1380C
Featuring high temperature tolerance,high flexural strength, good
oxidation and wear resistance, sisic ceramic rollers can be used
for a long term without fracture or bend.
The rollers are widely applicable in roller kilns for domestic
ceramics, sanitary ceramics, building ceramics, and magnetic
materials.
This is reaction bonded (silicon infiltraded) silicon carbide,
being formed zero porosity by filling up open porosity with silicon
metal (si).
Because of it's zero porosity characteristic, thermal conductivity
is more than twice of Oxide Bonded SiC's, bending strength is more
than 5 times higher comparing to Oxide Bonded SiC.
SiSiC's sepecial feature is its ability to maintain high strength
from room temperature up to 1,350C. Also it has very high oxidation
resistance, chemical resistance and wear resistance.
Used as beam, roller, radiant tube burner and burner nozzle etc.
