In - Depth Analysis: The Unique Advantages of Fused Silica Bricks in the Upper Wall of Kilns

In the field of industrial kilns, the choice of refractory materials is crucial for ensuring the safe and stable operation of kilns. Fused silica bricks have emerged as an excellent option for use in the upper wall of kilns, offering a range of unique advantages that make them stand out in the market.

Product Advantages and Their Role in Kiln Operation

Fused silica bricks are known for their high purity. With a silica content of over 99%, they are extremely resistant to chemical corrosion. In a kiln environment, where various corrosive substances may be present, this high - purity characteristic helps the bricks maintain their structural integrity. For example, in a glass - making kiln, the acidic and alkaline substances generated during the melting process can cause severe corrosion to ordinary bricks. However, fused silica bricks can withstand these corrosive attacks, reducing the frequency of brick replacement and maintenance costs.

Another significant advantage is their small thermal expansion coefficient. Generally, the thermal expansion coefficient of fused silica bricks is about 0.5×10⁻⁶/°C. This means that during the heating and cooling cycles of the kiln, the bricks will not expand or contract significantly, which helps to prevent cracks and damage to the kiln structure. As a result, the overall safety and stability of the kiln are greatly enhanced.

Suitability for Low - Alkali Borosilicate Glass Construction

Low - alkali borosilicate glass is widely used in high - end glass products due to its excellent thermal stability and chemical resistance. When constructing kilns for low - alkali borosilicate glass production, fused silica bricks are the ideal choice. Their high - temperature resistance and chemical stability match well with the requirements of the glass - making process. For instance, in the production of low - alkali borosilicate glass, the kiln temperature can reach up to 1500°C. Fused silica bricks can maintain their physical and chemical properties at this high temperature, ensuring the quality and consistency of the glass production.
