Fabrication of Clay Foam Ceramics Using Silicon Carbide and Ferric Oxide as Foaming Agents
In this paper a foam ceramic was prepared from clay, silicon carbide, ferric oxide, feldspar and other raw materials. The content of ferric oxide and the powder size of silicon carbide influenced the sinter behavior of the foam ceramics. The ferric oxide and feldspar are favorable to form of glass phase in the ceramics. The foam ceramics with the rate of moisture absorption is less than 0.05%, the bulk density is 0.3~0.9g/cm3, and compressive strength is over than 2MPa.
