Microporous silica boards are advanced insulation materials composed of highly pure amorphous silica, which is a mineral compound made of silicon and oxygen. These boards have a highly porous structure, with pore sizes ranging from nanometers to micrometers, which gives them unique thermal insulation properties. Microporous silica boards are commonly used in high-temperature applications, such as furnaces and kilns, due to their exceptional thermal stability and resistance to thermal shock.
