Introduction:
High Thermal Conductivity Silica Dense Refractory Brick Silica-based heat-insulating refractory bricks refer to heat-insulating refractory products made of silica as the main raw material and with an SiO2 content of not less than 91%. In addition to the thermal insulation properties of silicon refractory bricks, it maintains the characteristics of silicon bricks to a large extent. The starting temperature of load softening is high, and the volume expands slightly during the heating process, which enhances the integrity of the kiln. The manufacture of siliceous heat-insulating refractory bricks uses finely pulverized silica as the raw material, adding part of the waste silica bricks or waste siliceous heat-insulating refractory brick powder, mineralizers and burnout additives. Add water to the mixer according to a certain proportion to mix into a mud, which is formed by mechanical or manual molding. After the brick is dried, the residual moisture is less than 0.5% before it can be loaded into the kiln. In order to prevent the violent volume expansion due to the polycrystalline transformation of SiO2, causing cracks in the product, a slower temperature rise and fall speed are required during firing.

High Thermal Conductivity Silica Dense Refractory Brick :
1) Silicon oxide is above 94%.
2) Good acid erosion resistance.
3) High softening point

Package:

High Thermal Conductivity Silica Dense Refractory Brick are packed on wooden pallet and then polyethylene film is placed over it,finally the package is tied up with steel strips or as your request
