Introduction to Alumina Foam Filter
Alumina foam filter is a high-efficiency filtration device made of porous materials, mainly used in industrial production and laboratories. It is made of high-purity alumina sintered by a special process to form a foam body with a three-dimensional network structure. This structure not only provides a large surface area but also has good mechanical strength and chemical stability, making it an ideal choice for a variety of filtration applications.
