About Silica Bricks

Silica Bricks

Silica bricks are acid refractory materials with good resistant ability to acid slag.The SiO2 content of silica brick takes up 94%. The larger amount of the SiO2 content of silica raw materials, the higher the refractoriness. We are a leading Manufacture, Supplier and Exporter of Best Quality of Silica brick as per the customer's needs and requirements.

The silica bricks have the good ability to keep volume stable at high temperature for a long time. Its properties include good corrosion resistance of acid slag,good air tightness and good stability under the high temperature. The mineral composition of silica brick is mainly tridymite, cristobalite, a small amount of quartz and glass matrix. Silica brick offered by CMS INDUSTRIES is known forits chemical and physical properties in the foreign markets.

Superior Thermal Stability for Industrial Furnaces

Silica Bricks exhibit significant thermal expansion above 1390C, but maintain excellent dimensional stability even in demanding environments. Their acid refractory nature and resistance to chemical attack ensure reliable performance in furnaces, glass manufacturing, steel plants, and coke ovens. With a refractoriness under load of at least 1400C, these bricks provide durable protection for your heat-intensive operations.

High Purity SiO2 Content Guarantees Longevity

Containing more than 95% SiO2, Silica Bricks are engineered for outstanding refractoriness and low permanent linear change, even at temperatures reaching 1450C. The superior chemical composition supports extended service life and optimal performance under aggressive conditions encountered in thermal processing industries, ensuring value for your investment.

Customizable Sizes and Shapes for Diverse Applications

Whether your project demands the standard 230mm x 114mm x 65mm size or tailored dimensions, Silica Bricks can be manufactured to fit specific design requirements, including rectangular and arch forms. This flexibility enables seamless integration into various furnace designs. Transportation is streamlined with wooden pallet and export packaging, minimizing breakage during shipping.

FAQ's of Silica Bricks:

Q: How are Silica Bricks manufactured for high-temperature applications?

A: Silica Bricks are produced by pressing raw materials containing high-purity SiO2, followed by firing them at elevated temperatures. This process imparts unique properties such as excellent dimensional stability and resistance to acid slag in thermal environments.

Q: What is the main benefit of using Silica Bricks in thermal processing industries?

A: The main benefit is their high refractoriness under load (minimum 1400C), which ensures the bricks retain strength, resist chemical attack, and provide long-lasting insulation in high-temperature furnaces like glass plants, coke ovens, and steel manufacturing units.

Q: Where can Silica Bricks be effectively used?

A: They are widely used as lining materials in furnaces, glass manufacturing units, steel plants, coke ovens, hot blast stoves, and electric arc furnaces, thanks to their durability and acid refractory nature.

Q: What sizes and shapes of Silica Bricks are available?

A: The standard size offered is 230mm x 114mm x 65mm, but custom sizes and shapes-including rectangular, arch, and other configurations-can be manufactured to cater to specific requirements.

Q: What chemical composition ensures the durability of Silica Bricks?

A: Silica Bricks comprise over 95% SiO2 along with minor components like Fe2O3, Al2O3, and CaO. This composition contributes to their exceptional acid resistance and mechanical strength at high temperatures.

Q: How does significant thermal expansion affect the usage of Silica Bricks?

A: Although Silica Bricks exhibit significant thermal expansion above 1390C, their excellent dimensional stability at high temperature ensures consistent and safe performance as refractory linings within industrial settings.

Q: What packaging is used for exporting Silica Bricks internationally?

A: For safe transport, Silica Bricks are packed on wooden pallets or in standard export packaging, which provides enhanced protection against breakage during shipping and delivery.
