Detailed introduction
Product Introduction
In high-temperature industrial sectors such as steel, ceramics, and glass, a refractory material known as lightweight mullite bricks is quietly transforming traditional production processes. These lightweight refractory bricks, whose primary crystalline phase is mullite (3Al₂O₃·2SiO₂), have become a key material for energy conservation and consumption reduction in high-temperature kilns, thanks to their properties of low thermal conductivity, high strength, and excellent resistance to thermal shock.
