Product Information

Silicon bricks are a refractory product with silicon dioxide as the main component and its content is more than 94%. It belongs to acid refractory material, so it has strong resistance to acid slag erosion and has higher softening temperature under load.

Features

It has strong corrosion resistance to acidic slag and has a high load softening temperature. Silica bricks will undergo irreversible volume expansion when heated below 600°C, which will make the joints close and ensure good air tightness and structural strength of the masonry.
