Abstract:
     This invention describes a coating and process by using vacuum evaporation technology and controlling evaporative atmosphere and pressure to manufacture a type of black aluminium coating with an improved spectrum selectivity, that is, more than 0.87 solar energy absorption rate and more than 0.13 infra-red emissing ability, and suited to manifold bottom materials of metal and glass and organic materials. Large dimensional and continuous production can be realized by using a simple process.
