Sintering processes as well as all industrial processes depend on conventional energies. This work tries to demonstrate the feasibility of the application of a renewable power source, as Thermal Solar Energy, in copper sintering. In order to evaluate in the future driving forces and transported material path according to characteristics of the system and the incident radiation, different experimental devices based on ideal particle models, cylinders in this case, were designed to simplify the real system geometry based on compact powders. These devices were evaluated in the Plataforma Solar de Almería (PSA) Solar Furnace. Later analysis of the test pieces showed the feasibility of sintering copper in solar furnaces, the test pieces, treated in slightly reducing atmosphere, have developed well-defined necks and reduced porosity, which are typical characteristics of sintering.
