Alumina ceramic foam bricks are lightweight and porous ceramic structures made from alumina-based materials. They feature a cellular or foam-like structure with interconnected pores, providing a high surface area-to-volume ratio.
It has excellent resistance to corrosion and corrosion of molten aluminum, so it can effectively remove inclusions. Due to its lightweight and low thermal conductivity, the foamed alumina has less accumulated heat energy and an excellent energy-saving effect. The precise appearance dimensions of alumina filter bricks can speed up the masonry speed and ensure high strength and stability of the masonry.
- Higher strength than refractory ceramic fiber and a lightweight ceramic brick.
- Low density
- Low thermal conductivity and linear thermal expansion coefficient.
- Great thermal shock resistance.
- Safe and rapid maintenance.
