Nickel foam is a kind of sound absorption material with excellent performance, which has a high sound absorption coefficient at high frequency; through the design of sound absorption structure, its sound absorption performance at low frequency can be improved. Foam nickel is also one of the best electrode materials for manufacturing cadmium-nickel batteries and hydrogen-nickel batteries. The proce...

The development of foam ceramic materials began in 1970s, and is a porous material with high temperature characteristics. Its pore size ranges from nanometer to micron, and its porosity ranges from 20% to 95%, and its service temperature is from room temperature to 1600 ℃. Generally, foam ceramics can be divided into two categories, namely, open hole (net) ceramic material and closed cell ceramic ...

1.1 foaming method: the foaming reaction method can be used to prepare foamed ceramic products with complex shapes to meet the applications of some special occasions. Adding proper ceramic fibers into ceramic powder can improve the process and effectively increase the strength of the billet in sintering process so as to avoid chalking and collapse. 1.2 sol-gel method: sol-gel method is mainly used...

Composite metal foams (CMFs) are enough to turn an armor-piercing projectile shot at it into powder. These foams are lighter than materials reinforced with metal coatings, which are more suitable for the manufacture of new types of car bodies and the assembly of vehicle armor-and these are just the tip of the iceberg of its potential uses. Composite metal foam (pictured) is a type of steel support...
