Detailed Product Description
1. 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.
2. 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 1700.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.
3. 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.
4. 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.
5.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 input 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 15%, saving energy and protecting environment
