Fused silica brick is also called zero-expansion silica brick or thermal shock-resistant silica brick. They have extremely low thermal expansion coefficient, excellent resistance to rapid cooling and rapid heating, and good high-temperature performance. They are widely used in the rapid repair of various coke ovens.
