Description
Technical Parameters

Refractory zirconia bricks are a high-performance refractory material commonly used in the refractory industry. They have many excellent properties. This article will focus on the characteristics of zirconia refractory bricks.

 

First of all, zirconia refractory bricks have extremely high fire resistance. Zirconia itself is a high-temperature material with a melting point of over 2700°C. Therefore, zirconia refractory bricks also have extremely high fire resistance and can withstand harsh conditions at high temperatures.

 

Secondly, zirconia refractory bricks have excellent chemical stability. Since zirconia itself is not easy to react at high temperatures, zirconia refractory bricks can remain stable in chemical media such as acids and alkalis and are not susceptible to corrosion.

 

Furthermore, the thermal expansion coefficient of zirconia refractory bricks is low, which can avoid cracking and deformation caused by thermal expansion and contraction. At the same time, its thermal conductivity is also low, making it difficult to conduct heat under high temperature conditions, which is beneficial to maintaining the thermal stability of the equipment.

 

In addition, zirconia refractory bricks have excellent wear resistance and impact resistance. At high temperatures, zirconia refractory bricks have good structural stability, are not susceptible to mechanical impact and wear, and can maintain a long service life.

 

Finally, the lighter density of refractory zirconia bricks makes them easier to install and use. Due to its low thermal conductivity, it can also reduce the impact of thermal stress, which ensures the life and safety of the equipment.

 

In short, refractory zirconia bricks are a rare high-performance refractory material with excellent fire resistance, good chemical stability, low thermal expansion coefficient, good impact resistance, light density, etc., and have broad application prospects. We are committed to providing our customers with the highest quality zirconia refractory bricks and other refractory materials.
