Light Weight Mullite Bricks
Product Information
The main components of lightweight mullite bricks include aluminum oxide (Al₂O₃) and silicon dioxide (SiO₂), and its main crystal phase is mullite (3Al₂O₃·2SiO₂). During the manufacturing process, a foaming agent and a stabilizer are usually used to mix the slurry, and after pouring, curing, drying, baking and firing, a lightweight brick with high porosity is finally made.
