Zero expansion silica bricks are high thermal shock resistance zero expansion silica bricks made of fused quartz as the main raw material. They have many advantages such as thermal shock resistance, high strength, low expansion rate, and acid corrosion resistance when heated. They are the best choice for glass kiln hot repair bricks. Zero expansion silica bricks have the advantages of low expansion rate and strong thermal shock resistance. They are specially designed for hot repair of coke ovens and glass kilns. They can be repaired during the operation of the kiln without stopping the operation of the kiln. No expansion joints need to be reserved during masonry, which is an ideal product for hot repair of coke ovens. This product has the characteristics of high thermal shock resistance, low expansion, high SiO2 content, and good density, and is particularly suitable for hot repair of coke ovens.
