In the alkaline industries, such as glass kilns, finding the right refractory materials is crucial for ensuring stable operation, longevity, and energy efficiency. Magnesium-zirconium bricks have emerged as a new and promising choice for these industries. Let's explore their unique features, performance advantages, and real-world applications.

Unique Composition and Alkaline Resistance

Magnesium-zirconium bricks are made from a combination of fused magnesia and zircon sand. This innovative combination is the key to their excellent alkaline resistance. Fused magnesia has high refractoriness and good chemical stability, while zircon sand can form a dense structure that effectively resists the penetration of alkaline gases and slag. When exposed to the harsh alkaline environment in glass kilns, this unique composition allows magnesium-zirconium bricks to maintain their integrity and performance.

High Density and Its Benefits

One of the core advantages of magnesium-zirconium bricks is their high density, with a bulk density greater than 3.08 g/cm³. This high density brings several important properties:

• Anti-erosion: The dense structure can effectively resist the erosion of alkaline slag, reducing the wear and tear of the bricks and extending their service life. For example, in a glass kiln with high alkali content, traditional bricks may be eroded by slag at a rate of 5 - 10 mm per year, while magnesium-zirconium bricks can reduce this erosion rate to less than 2 mm per year.
• Anti-spalling: It has better thermal shock resistance, which can prevent the bricks from spalling under rapid temperature changes. In a glass kiln where the temperature fluctuates frequently during the melting and cooling processes, magnesium-zirconium bricks can maintain their structural integrity better than traditional bricks.
• High-temperature resistance: Magnesium-zirconium bricks can withstand high temperatures up to 1700°C, ensuring stable operation in high-temperature glass kilns.

Addressing Pain Points in Glass Kilns

Traditional refractory materials in glass kilns often face several pain points. For instance, they may have poor alkaline resistance, leading to frequent replacement and high maintenance costs. Also, their low thermal shock resistance may cause spalling and affect the normal operation of the kiln. Magnesium-zirconium bricks can solve these problems. Their excellent alkaline resistance reduces the need for frequent replacement, and their high thermal shock resistance ensures stable operation even under complex temperature conditions.

Comparison with Traditional Bricks

As shown in the table, magnesium-zirconium bricks have significant advantages in terms of alkaline resistance, environmental friendliness, and long-term cost-effectiveness compared to traditional magnesia-chrome bricks and corundum bricks.
