Introduction to Silica Bricks
Silica bricks are a type of refractory material that are mainly composed of silica (SiO₂). They are widely used in various high - temperature industrial applications due to their excellent thermal properties. With a high melting point, typically around 1690 - 1730 °C, silica bricks can withstand extreme heat without significant deformation. They have a relatively low thermal expansion coefficient, which means they can maintain their shape and integrity during repeated heating and cooling cycles. This makes them ideal for use in furnaces, kilns, and other high - temperature equipment in industries such as steelmaking, glass manufacturing, and cement production.
