Ceramic Foam

Ceramic foam is a porous material with high-temperature properties. This material is characterized by a wide range of pore sizes, ranging from nanoscale to microscale, porosities between 20% and 95%, and a wide range of service temperatures, ranging from room temperature to 1600°C. Ceramic foams can be categorized into open-cell (reticulated) ceramic materials and closed-cell ceramic materials based on whether or not the pores have solid walls. The interior of ceramic foams is filled with a large number of pores that are highly connected, allowing the foam ceramics to transfer gases and liquids well. Due to their excellent high-temperature properties, foam ceramics can be used in high-temperature environments without pyrolysis or sintering.

In addition, ceramic foams can be classified into various types according to the material, including but not limited to magnesium oxide foam ceramics and the like. They are used in a wide range of applications including, but not limited to, filtration of casting alloys, fabrication of partition walls, and the like. Due to their unique properties and wide range of applications, ceramic foams play an important role in the industrial and construction fields
