Shock! This High - quality Silica Brick for Glass Kilns Becomes the New Favorite for High - temperature Refractory Applications

In the field of glass manufacturing, the refractory materials used in the high - temperature parts of glass kilns play a crucial role. The quality of these materials directly affects the efficiency, service life, and product quality of the glass kiln. Recently, a high - quality silica brick specifically designed for the high - temperature parts of glass kilns has emerged as the new favorite in the market.

Composition of the Silica Brick

This silica brick is mainly composed of tridymite and cristobalite. The raw material is natural silica sand with an SiO₂ content of over 96%. The high SiO₂ content provides a solid foundation for its excellent performance. The unique crystal structure of tridymite and cristobalite endows the silica brick with special physical and chemical properties.

Performance Advantages of the Silica Brick

High - temperature resistance: It can withstand temperatures up to 1650°C. In the high - temperature environment of glass kilns, where the temperature often exceeds 1500°C, this silica brick remains stable, ensuring the normal operation of the kiln. For example, in a large - scale glass factory in Germany, after using this silica brick in the high - temperature melting zone of the glass kiln, the kiln can operate continuously at 1600°C for more than 200 days without significant damage.

Volume stability at high temperatures: During the heating and cooling process, the volume change of this silica brick is less than 0.5%. This small volume change prevents the formation of cracks in the kiln lining, which is essential for maintaining the integrity of the glass kiln structure. According to a research report from a well - known refractory materials research institution, the volume stability of this silica brick is 30% better than that of ordinary refractory materials.

No pollution to glass liquid: The chemical composition of this silica brick is very pure. It does not react with the glass liquid, ensuring the high quality of the glass product. In a domestic glass manufacturing enterprise, after replacing the original refractory materials with this silica brick, the defect rate of the glass products decreased by 15%.

Strong chemical corrosion resistance: It can resist the corrosion of various alkaline and acidic substances in the glass kiln. In the harsh chemical environment of glass production, this property extends the service life of the refractory materials. Tests have shown that its corrosion resistance is 2.5 times that of common refractory bricks.

Low density: With a density of only 1.8 g/cm³, it reduces the load on the glass kiln structure. This not only saves energy during the operation of the kiln but also reduces the construction cost of the kiln.

Proven by Experiments and Cases

Many experiments and practical applications have verified the excellent performance of this silica brick. A series of laboratory tests have shown that under the same high - temperature and chemical corrosion conditions, the service life of this silica brick is 1.5 - 2 times that of other similar products. In addition, numerous glass manufacturers around the world, such as those in the United States, Japan, and China, have given positive feedback after using this silica brick.

Conclusion and Call to Action

In conclusion, this high - quality silica brick for glass kilns has significant advantages in terms of composition and performance. Its high - temperature resistance, volume stability, non - pollution to glass liquid, chemical corrosion resistance, and low density make it the ideal choice for the high - temperature parts of glass kilns. If you are a glass manufacturer looking for high - performance refractory materials for your glass kiln, don't miss this opportunity. Choose this silica brick and experience a new level of glass production efficiency and quality.
