1. Thermal insulation
- Foam ceramic sheets have a porous structure. These pores are filled with air. Air is a poor conductor of heat. As a result, the foam ceramic sheets can effectively reduce the transfer of heat. For example, in the construction industry, they can be used in the outer walls of buildings. By installing foam ceramic sheets, the indoor temperature can be better maintained, reducing the need for excessive use of heating in winter and air – conditioning in summer, thus saving energy and reducing costs.

2. Sound absorption and noise reduction
- The porous nature of the foam ceramic sheets also enables them to absorb sound waves. When sound waves enter the pores, they are repeatedly reflected and scattered inside the pores. Some of the sound energy is converted into heat energy due to friction and other effects, thereby reducing the intensity of the sound. In industrial settings, such as factories or near highways, foam ceramic sheets can be used to build sound – insulating barriers to reduce noise pollution and create a relatively quiet environment for nearby residents and workers.
3. Filtration
- The pores of the foam ceramic sheets can act as a filter medium. They can filter out particulate matter and impurities from gases or liquids. For instance, in the field of environmental protection, they can be used in the filtration of industrial waste gases. The complex pore structure can trap harmful particles such as dust, soot, and some heavy metal particles, purifying the gas before it is discharged into the atmosphere. In liquid filtration, they can be used to filter out solid impurities in solutions, playing an important role in water treatment and chemical process filtration.
4. Catalytic support
- The high – surface – area – to – volume ratio of foam ceramic sheets makes them excellent carriers for catalysts. The large surface area provides more sites for the attachment of catalyst particles. When used in chemical reactions such as in the chemical industry or automotive exhaust treatment, the catalyst – loaded foam ceramic sheets can enhance the contact between the reactants and the catalyst, improving the efficiency of the catalytic reaction. For example, in automotive catalytic converters, the foam ceramic sheets can support precious – metal catalysts (such as platinum, palladium, and rhodium) to help convert harmful pollutants in exhaust gases (such as carbon monoxide, hydrocarbons, and nitrogen oxides) into less harmful substances.
