Performance Indicators Of High Thermal Conductivity Silica Bricks

Performance indicators of high thermal conductivity silica bricks

Compared with traditional silica bricks, high thermal conductivity silica bricks have made significant improvements in structural morphology, crystal structure, and physicochemical indicators.

The structural morphology of high thermal conductivity silica bricks. After comparing the structural morphology of high thermal conductivity silica bricks with traditional silica bricks at a magnification of 20 times, it was found that the pore size of high thermal conductivity silica bricks is smaller and the distribution is more uniform The gas inside the pores has 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.
The content of scale quartz in high thermal conductivity silicon bricks is 70%, while that in traditional silicon bricks is 60%. The content of scale quartz in high thermal conductivity silicon bricks is 10% higher than that in traditional building bricks. Scale quartz has a pointed twin crystal structure, which is very dense and conducive to improving thermal conductivity.

After improving the thermal conductivity of high thermal conductivity silica bricks, other performance indicators are consistent with traditional coke oven silica bricks. That is to say, high thermal conductivity silica bricks inherit the advantages of traditional coke oven silica bricks and further highlight their high thermal conductivity characteristics. It can be seen that the various performance aspects of high thermal conductivity silica bricks are balanced.
