Product DescriptionÂ
     Silicon nitride (Si3N4) bonded
silicon carbide (SiC) material is produced by adding industrial
silicon paste into artificial aggregate. Under high
temperature, Si and N2 reacts with the formula of
2N2*3Si=Si3N4, Si3N4 bonded Sic material is formed by bonding
SiC particles tightly. Therefore, Si3N4 bonded SiC material is
an excellent refractory with the original properties of SiC.
The material has quite high strength even under the temperature
of ***0.C has properties of creep deformation resistance and
anti-chemical erosion, and has excellent thermal conductivity
and wear-resistance. Comparing with other several bonded SiC
materials, Si3N4 bonded SiC material has attracted more and
more attention.Â

FeatureÂ
     Si3N4
Bonded SiC material is mainly used in the production of
aluminum, copper and zinc , as the lining material of the
molten pool and electrolytic bath (reduction bath). The side
lining of the reduction bath is eroding by aluminum and
cryolite (used as additive), but Si3N4 bonded SiC material
could not be eroded by aluminum, and do not have chemical
reaction with cryolite. So this kind of material is ideal for
the lining bricks of the electrolytic bath. In particular this
kind of bricks have the excellent properties of high strength,
abrasive resistance and nonconductive, so the copolymer (Al2O3
and Cryolite). The copolymer likes protective film to protect
the working lining and improve the service life of electrolytic
bath. At the same time, the Si3N4 bonded SiC bricks have lower
thermal conductivity than silicon bricks, so they can reduce
the thickness of the side wall or higher power to expanse
the loading capacity of the electrolytic bath, and to increase
the output. Because of the high resistivity of the material, it
can reduce the power consumption of the side -wall about *5%,
saving energy and protecting environment
