The Role of Adding Zirconia to Corundum Bricks

The main function of adding zirconia to corundum bricks is to enhance their performance and durability.

Zirconia is an important refractory material with various characteristics:

High melting point: Zirconia has a high melting point, about 2700 degrees Celsius, allowing it to maintain stability in high-temperature environments.

Excellent heat resistance: Due to its high melting point and thermal stability, zirconia is often used in high-temperature industrial applications, such as refractory materials, thermal insulation materials, etc.

Excellent chemical stability: Zirconia has good corrosion resistance to chemicals such as acids and alkalis, making it widely used in the chemical industry.

High hardness: Zirconia has a high hardness, close to steel, giving it good wear resistance in friction and wear environments.

Excellent electrical properties: Zirconia is a dielectric with good insulation properties and is widely used in the insulation layer of electronic devices.

Biocompatibility: Zirconia is widely used in the medical field because it has good compatibility with biological tissues and is suitable for use in medical devices such as human bone repair.

High refractive index: Zirconia has a high refractive index, which makes it widely used in the optical field, such as optical lenses, laser devices, etc.

Overall, zirconia is a multifunctional material with excellent physical, chemical, and mechanical properties and has a wide range of applications in various fields.

Zirconia can improve the physical and chemical properties of corundum bricks, making them more resistant to high temperatures, wear, and corrosion. This makes corundum bricks have a longer service life in high-temperature environments and are more suitable for various industrial applications, such as high-temperature furnace linings, refractory bricks, etc. Adding zirconia can also improve the thermal shock stability of corundum bricks and reduce cracks and damage that occur during rapid temperature changes. Therefore, the addition of zirconia can improve the overall performance of corundum bricks, making them more suitable for harsh industrial environments.
