Product Details

The company is currently using a special process to produce new products-high density, high thermal conductivity, high corrosion resistance silica brick. The product is added with dispersed nanomaterials and special substances that can improve the thermal conductivity, thereby greatly improving the corrosion resistance, thermal conductivity and wear resistance of the silica brick.

Product features:

1ProductsSiO2High content (≥95%), good high temperature volume stability.

The improvement of thermal conductivity can greatly reduce the consumption of raw materials. Thus, the emission of harmful gases can be further reduced.

3, corrosion resistance, wear resistance, resistance to harmful substances and alkaline metals and other damage caused by silica brick.

4, can greatly improve its service life, reduce costs.
