In order to guide the healthy and orderly development of energy saving wall material, all kinds of wall material are analyzed comprehensively basing on the various possible indexes which affect the performance of wall material.
For a long time, solid clay brick still prevails in wall materials in china.
The evaluation of wall material The selecting evaluation object is the exterior wall material which has some production scale.

Laser forming, an advanced technology widely used for the shaping and adjustment of metallic and non-metallic materials, can also be used to process metal/ceramic materials.
Introduction Metal/ceramics bilayer materials are materials of great interest that are commonly used in helmets, personal body armors [1, 2] and for aerospace.
