Zero Expansion Silica Bricks are a special type of silica refractory material with an extremely low thermal expansion coefficient, making them almost dimensionally stable even under high temperatures. This characteristic makes them particularly suitable for repair and maintenance work in high-temperature environments like glass kilns. Here are the key features and applications of zero expansion silica bricks in the context of glass kiln repair:
Zero expansion silica bricks are primarily used in the following areas during glass kiln repair:
