Product Information
High-quality fused silica bricks made of pure silica for demanding applications. Fused silica bricks feature high purity, high strength, extreme temperature resistance, low thermal expansion, and superior thermal shock resistance.
Ideal for glass furnaces, kilns, and other high-temperature applications where durability and performance are critical. Fused silica bricks provide an exceptional combination of properties for many industrial uses.
Fused silica bricks are made of fused quartz, which is one of the purest forms of silica, made by melting naturally occurring quartz crystals and cooling them into a glass. This results in a material with very high purity, over 99% silica.
