Curious! What Are the Advantages of Fused Silica Bricks Compared to Other Kiln Materials?

In the glass production industry, the performance of kilns plays a crucial role in determining the quality and efficiency of glass manufacturing. The choice of kiln materials directly affects the overall performance of the kiln. Today, we will focus on fused silica bricks and compare them with other common kiln materials to explore their unique advantages.

Unique Characteristics of Fused Silica Bricks

Fused silica bricks are known for their high purity. Typically, the silica content in fused silica bricks can reach over 99%. This high - purity characteristic makes them highly resistant to chemical corrosion. In the harsh chemical environment of glass kilns, they can effectively resist the erosion of various alkaline substances and other corrosive media, ensuring the long - term stable operation of the kiln.

Another significant advantage is their small thermal expansion coefficient. The thermal expansion coefficient of fused silica bricks is approximately 0.5×10⁻⁶/°C. During the heating and cooling process of the kiln, a small thermal expansion coefficient means less internal stress generated in the bricks. This reduces the risk of brick cracking and spalling, greatly extending the service life of the kiln lining.

These characteristics of fused silica bricks can significantly improve the performance of glass kilns. For example, their high - purity and corrosion - resistant nature can prevent impurities from entering the glass melt, thereby improving the quality of the glass product. The small thermal expansion coefficient ensures the stability of the kiln structure, reducing maintenance costs and downtime.

Real - world Application Cases and Data

Let's look at some real - world cases. A glass production enterprise replaced the original kiln lining materials with fused silica bricks. After a period of operation, it was found that the service life of the kiln lining was extended from the original 3 years to 5 years. This means a significant reduction in the frequency of kiln repairs and replacements, saving a large amount of cost for the enterprise.

In terms of product quality, the defective rate of glass products decreased from 8% to 3% after using fused silica bricks. This shows that fused silica bricks can effectively improve the quality and yield of glass products, bringing more economic benefits to the enterprise.

Comparison with Other Common Kiln Materials

When compared with other common kiln materials such as clay bricks and magnesia - chrome bricks, fused silica bricks have obvious advantages. Clay bricks have relatively low purity and poor corrosion resistance. In high - temperature and corrosive environments, they are prone to damage, and their service life is relatively short. Magnesia - chrome bricks, although having good high - temperature performance, may release chromium - containing substances under certain conditions, which is not environmentally friendly.

In contrast, fused silica bricks are not only high - purity and corrosion - resistant but also environmentally friendly. They are especially suitable for the construction of low - alkali borosilicate glass kilns, which can meet the strict requirements of high - quality glass production.

Conclusion and Invitation

In conclusion, fused silica bricks have outstanding advantages in terms of purity, thermal expansion coefficient, corrosion resistance, and environmental friendliness. They can effectively improve the performance of glass kilns, extend the service life of kilns, and improve the quality of glass products.
