Preparation and Applications of Foam Ceramics

Abstract

As a new type of porous material, foam ceramics have properties such as the high strength and hardness, the good plastic toughness, corrosion resistance and the high temperature resistance. This paper summarizes the preparation methods of foam ceramics such as organic foam impregnating method, foaming method, freeze-drying method, etc. The paper also introduces development status of foam ceramics at home and abroad as well as the application of foam ceramics in environmental protection, metal casting, construction and other fields. Finally, the current situation and developments of foam ceramics are discussed.
