Dense zircon fire bricks are mainly made of zircon (zirconium oxide, ZrO₂). Zircon is a material with a very high melting point and is usually mixed with other refractory materials (such as
bauxite, silica sand, etc.) to improve its performance. Dense zircon fire bricks have good corrosion resistance to molten glass and are mostly used for glass melting furnaces. In addition, dense
zircon bricks have high compactness and low porosity, excellent mechanical strength and corrosion resistance to molten glass.

Features of Dense zircon fire bricks:
1. High refractory: Dense zircon refractory bricks can withstand extremely high temperatures, with a melting point usually around 2700°C.
2. Excellent chemical corrosion resistance: Zircon has very strong corrosion resistance to many chemical media (such as molten metal, molten glass, acid and alkali).
3. High mechanical strength: Dense zircon refractory bricks maintain high mechanical strength and wear resistance at high temperatures, and are suitable for high-temperature application scenarios that require high strength.
4. Thermal stability: It has good thermal stability and can maintain stable performance in an environment with drastic temperature changes.
Application of Dense zircon refractory bricks:
1. Masonry drum lining for degassing, stainless steel drum lining, Cleaning a continuous cast steel drum, sprue brick, plug brick and lining of high temperature induction furnace.
2. Glass melting furnace: Dense zircon refractory bricks are often used in glass melting furnaces due to their excellent resistance to molten glass corrosion.
3. Arc furnace: Used in the lining of arc furnaces, it can withstand the erosion of high-temperature arcs and molten metals.
4. Petrochemical reactor: Used in high-temperature reactors in petrochemical and fertilizer production, it can withstand the corrosion of chemical media.
5. Ceramic kiln: Used in the lining of high-temperature ceramic kilns to maintain high-temperature stability and wear resistance.
About transportation of zircon bricks
Zircon bricks are packed on wooden pallets before transportation. The delivery time to the factory is usually 7-12 days, and making custom-made products takes longer.
