Product Description
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.

Feature
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
