Silicon carbide brick is a refractory material made of SiC as the main raw material.
Mohs hardness is 9.
It is more stable for acid slag.
Containing SiC 72% ~ 99%.
It is divided into clay bonded, Si3N4 bonded, Sialon bonded, β -sic bonded, Si2ON2 bonded and recrystallized silicon carbide bricks.
Mainly used in non-ferrous metallurgy retort, cast aluminum mold, electric furnace lining and heat exchanger, etc.
Silicon carbide as the main raw material made of refractory products.
Silicon carbide content 72% ~ 99%.
The general selection of black silicon carbide (SiC content of 96% or more) as raw material, adding binder (or no binder), the batching, mixing, molding and firing process.
The main crystal phase is silicon carbide.
The main varieties are oxide bonded silicon carbide bricks, carbon bonded silicon carbide bricks, nitride bonded silicon carbide bricks, self-bonded silicon carbide bricks, recrystallized silicon carbide bricks and semi-bonded silicon carbide bricks.
It is a high performance refractory material with good wear resistance, corrosion resistance, high temperature strength, good thermal shock stability, high thermal conductivity, small thermal expansion coefficient and other characteristics.
