Compared with traditional silica bricks, high thermal conductivity silica bricks have been greatly improved in terms of structural morphology, crystal structure, physical and chemical indicators, etc. After comparing the structure of high thermal conductivity silica bricks with that of traditional silica bricks by 20 times, it was found that the pore diameter of high thermal conductivity silica bricks is smaller and the distribution is more uniform. The gas in the pores has a lower thermal conductivity than the solid, so the pores always reduce the thermal conductivity of the material. Within a certain temperature range, for a certain porosity, the smaller the porosity, the stronger the thermal conductivity.
1. Good density, good durability and long service life.
2. The pores are small, evenly distributed, and have good thermal conductivity.
3.The thermal conductivity is better than traditional silica bricks.
4. Contains 70% flake quartz, 10% higher than traditional silica bricks, and has good thermal conductivity.
5. Balanced performance in all aspects, retaining the advantages of traditional silica bricks.
1. Coke oven, especially the carbonization chamber.
2. Coking industry.
3. High temperature industrial furnaces that require refractory materials with high thermal conductivity.
