Abstract: Different experiences described are related to research works based on the application of concentrated solar energy (CSE). The experiences described are associated with quenching processes, layer generation processes by means of powder melting (cladding), self-propagated synthesis to obtain intermetallics, the formation of nitride layers of titanium in an atmosphere of Nitrogen, nitriding of steel and cast iron, the sintering of metals and ceramics, some processes of reduction of oxides and of welding, allotropy of metallic solid solutions; every one using CSE as the heat source. There are also experiences related to hybrid heat source processes such as electric induction and CSE hardening. At the end of the description, an evaluation of all these possibilities is carried out and proposals are issued on those that seem most promising and viable at this time. 

  We believe that CSE has a very promising future as an important resource to be used in industrial processes according to the needs of a better environment, as a relevant way to reduce energy consumption taking advantage of the unique opportunities offered.


Key words: solar energy assisted processes, low environmental impact manufacturing proposals
