The materials are characterized by a manufacturing process that includes:
Blending coarse silicon carbide or Corundum (fused alumina) grains with ceramic and metallic powders,
pressing or casting the mix to the final shape,
firing the green body at high temperature under Nitrogen.
Integrated the best compositions and manufacturing know how of the former competitors: Norton, Carborundum, AnnaWerk and Savoie Refractaires, and developed a unique range of superior nitride bonded refractories.
The currently marketed materials are either silicon nitride, or silicon oxynitride, or SiAlON bonded.
The chemical formulas of the considered nitride bonds are:
Silicon nitride = Si3N4
Silicon oxynitride = Si2ON2
SiAlON = Si (6-x) Al x O x N (8-x), with x < 4.2
The good advantages of our Nitride Bonded Sic Brick are as follows:
1. Low thermal conductivity
2. Low thermal expansion
3. Excellent oxidation resistance
4. Excellent corrosion resistance
5. Long duration
- Q: What refractory material does cupola lining use?
- It's made of high quality refractory material: 1770 ~ 2000 centigrade.
- Q: What are the common thermal insulation materials for thermal conductivity?
- Aerogels are known to be the lightest solid materials in the world. It is made of nanometer silica aerogel as main material and is compounded by special process. The utility model has the advantages of high temperature resistance, low thermal conductivity, small density, high strength, green environment protection, waterproof and non inflammable performance. At the same time, with excellent sound insulation and shock absorption performance, it is now widely used in metallurgy, chemical, national defense, aerospace and other fields, is an indispensable high-performance insulation materials.

- In the procurement of high alumina brick, the first color, high quality aluminum brick, brick surface smooth, yellow color pale, four sides equal, no broken angle, no cracks.
- Q: How to test the aluminium bricks of high alumina refractory bricks?
- Before making bricks, the raw materials are usually tested and tested to see if the aluminum content is up to standard
- Q: What's the weight of the refractory bricks?
- Referred to as refractory brick. Refractory made from refractory clay or other refractory material. Light yellow or brownish. The utility model is mainly used for laying smelting furnaces, and can withstand high temperature between 1580 DEG C and 1770 DEG C. Also called brick. Refractory material of a certain shape and size. According to the preparation process can be divided into bricks, brick, electric melting brick, refractory insulating bricks (Rong Zhuzhuan);
