SI3N4 bonded SIC brick.
Stable chemical performance
High cold crushing strength
Good thermal shock stability
Good anti corrosion ability
It is mainly used in the production of aluminum,copper, zinc.
It is used as the liner of molten bath or electrobath.
SI3N4 SIC brick has no corrosion with metal aluminum, and has no chemical reaction with cryolite. It is the ideal material for electrobath lining brick.

- Q:What is the silica refractory products?
- Refractory brick with silica content greater than 90%.
- Q:What are the main constituents of refractory bricks?
- Refractory brick composition is mainly composed of a variety of aggregate or aggregate and one or more kinds of sticky agent composed of mixed powder particles, when used, must be mixed with one or more liquids, mixing evenly, with strong liquidity. Different refractory bricks are different, such as silicon, aluminum, clay and so on:
- Q:Glass kiln brick for physical and chemical indicators?
- Glass kiln with high quality silica brick products according to the standard JC/T615-1996, the single brick is divided into 3 grades: XBG-96, ZBG-96, DBG-96.
- Q:Physical solid waste disposal
- Preparation of silica brick pug, a certain amount of waste silica brick used to add ingredients, for the purpose of expansion and stress reduction products when firing, reduce cracks, improve the rate of finished products.
- Q:The difference between clay refractory bricks and refractory brick in the application.
- Brick bearing soft temperature and close to the melting point, high temperature strength, can be in high temperature (above 1400 degrees) under the condition of long-term use, but the anti alkali erosion ability, thermal shock stability is the worst, a scrap. The brick is generally used in the coke oven, glass kiln. Other industries basically do not use.
- Q:The specific content is what gb/t2608-2012 brick
- Quality assessment procedures, packaging, marking, transport, storage, and quality certificates. Suitable for siliceous refractory bricks.
- Q:Can iron oxide be used as refractory material?
- Iron oxide can not be used as refractory material, but it can be used as refractory additive. Iron oxide can be used as pigment
- Q:What is the effect of the content of silicon nitride in silicon nitride bonded silicon carbide brick on the use of electrobath? Thank you
- Small fluctuations in the chemical composition do not have a significant effect on use. The key is the operation of the electrolyzer in production to determine whether the side wall will be damaged.
- Q:Physical solid waste disposal
- Too much addition will reduce the refractory and mechanical strength, increase porosity, so the amount of waste brick should not be too much.
- Q:The brick is mainly used in the place?
- Partitions used in coking and combustion chambers for coke ovens
