Zirconia Refractory Bricks IntroductionZirconium refractory bricks/ Zirconia Bricks are high-end refractory materials primarily made from zirconium dioxide (ZrO2). Depending on the ZrO2 content, they can be divided into zircon bricks (ZrSiO4) and high-zirconium bricks based on stabilized zirconium dioxide. Due to their complex manufacturing process, which typically requires high-temperature sintering, zirconium refractory bricks are high-performance refractory products. Zirconium refractory bricks offer ultra-high refractoriness (2400°C), exceptional resistance to chemical attack, and excellent thermal shock resistance, playing an indispensable role in the most demanding high-temperature industrial environments, such as glass manufacturing, high-end metallurgy, and cement production.

Zirconia Refractory Bricks Features1. Extremely High Refractoriness: Their refractoriness typically exceeds 2400°C, far exceeding that of alumina-silicon refractories, enabling them to withstand extremely high operating temperatures. 2. Excellent Resistance to Slag Attack: They offer strong resistance to both acidic and alkaline slags, particularly against molten glass and molten metal. 3. Excellent Thermal Shock Resistance: Zirconium dioxide has a relatively low coefficient of thermal expansion and high fracture toughness, making zirconium bricks less susceptible to cracking or spalling under rapid temperature fluctuations. 4. High Mechanical Strength: Maintains excellent structural strength and wear resistance even at high temperatures. 5. Low Thermal Conductivity: Provides excellent thermal insulation in certain applications. 6. Chemical Inertness: Does not react with many molten metals and oxide-containing glass, ensuring product purity.
