Zircon refractory bricks are a type of refractory material that is made from zirconium oxide (ZrO2). They are known for their high strength, resistance to heat and corrosion, and thermal shock resistance. Zircon refractory bricks are used in a wide variety of high-temperature applications, including furnaces, kilns, power plants, and jet engines.



Types of Zircon Refractory Bricks

There are two main types of zircon refractory bricks:

• Zircon bricks: These bricks are made from a mixture of zirconium oxide and other materials, such as alumina, silica, and magnesia. Zircon bricks are known for their high strength and resistance to heat and corrosion. They are commonly used in the lining of furnaces and kilns.


• Zirconia-mullite bricks: These bricks are made from a mixture of zirconium oxide and mullite, a mineral that is formed from aluminum oxide and silica. Zirconia-mullite bricks are known for their high strength, resistance to heat and corrosion, and thermal shock resistance. They are commonly used in the lining of glass furnaces and other high-temperature equipment.

Applications of Zircon Refractory Bricks

Zircon refractory bricks are used in a wide variety of industries, including:

• Glass: Zircon refractory bricks are commonly used in the lining of glass furnaces. They are able to withstand the high temperatures and corrosive environments of glass production.


• Iron and steel: Zircon refractory bricks are used in the lining of blast furnaces, steel furnaces, and other high-temperature equipment in the iron and steel industry.


• Cement: Zircon refractory bricks are used in the lining of cement kilns. They are able to withstand the high temperatures and alkaline environments of cement production.


• Petrochemical: Zircon refractory bricks are used in the lining of reactors, crackers, and other high-temperature equipment in the petrochemical industry.


• Power generation: Zircon refractory bricks are used in the lining of boilers, furnaces, and other high-temperature equipment in the power generation industry.

Choosing the Right Zircon Refractory Brick

The choice of the right zircon refractory brick for a particular application depends on a number of factors, including:

• The operating temperature: The operating temperature is the most important factor to consider when choosing a zircon refractory brick. The refractory brick must have a melting point that is higher than the operating temperature.


• The chemical environment: The chemical environment refers to the chemicals to which the refractory brick will be exposed. The refractory brick must be resistant to attack from the chemicals in the environment.


• The desired mechanical properties: The desired mechanical properties will depend on the specific application. For example, some applications require high strength, while others require high thermal shock resistance.


• The cost: Zircon refractory bricks can vary widely in cost. The cost of the refractory brick must be balanced against the performance requirements of the application.

Tips for Choosing the Right Zircon Refractory Brick

Here are a few tips for choosing the right zircon refractory brick for your industry:

• Consult with a refractory expert: A refractory expert can help you assess your specific needs and recommend the right zircon refractory brick for your application.


• Consider the operating temperature and chemical environment: Make sure that the zircon refractory brick you choose can withstand the operating temperature and chemical environment of your application.


• Choose a reputable supplier: Only purchase zircon refractory bricks from a reputable supplier. This will help to ensure that you are getting a high-quality product.


• Inspect the bricks carefully: Before installing the zircon refractory bricks, inspect them carefully for any cracks or damage.


• Follow the installation instructions: Be sure to follow the manufacturer's installation instructions carefully. This will help to ensure that the bricks are installed properly and will perform as expected.

By following these tips, you can choose the right zircon refractory brick for your industry and ensure the safe and efficient operation of your equipment.

Zircon refractory bricks are an essential part of many industries, and they play a critical role in modern life. By understanding the properties and applications of zircon refractory bricks, engineers can select the right material for the job, ensuring the safe and efficient operation of equipment.
