**4. Conclusions**

The solar furnace can be used for numerous methods of technological purposes. The benefits that come from this sort of electrothermal installation is primarily based totally on sun electricity sources, and it could be utilized in various unique applications such as:


The researchers approach a dynamic thematic of high interest for problems consistency and for the wide area of applications.

*Assessment of Solar Energy Potential Limits within Solids on Heating-Melting Interval DOI: http://dx.doi.org/10.5772/intechopen.104847*

The results already achieved within this stage are also noted with the help of the collaboration with researchers from the renowned research institute from Almerian Solar Platform, Spain.

Objectives' fulfillment required an ample information activity. It was necessary to have a good control of some different mathematical methods as well as good information regarding the experimental research in materials' melting/burning/ purifying process.

The importance and complexity of this thematic make necessary detailed, interdisciplinary research. Thus, the team consists of specialists from the top domain of actual fundamental research such as materials science and physics.

The results already achieved open new work perspectives for the next year within the project in the approached thematic.

### **5. Perspectives**

The materials that can be studied are quartz, zirconium dioxide, corundum, ceramic oxides and materials like carbides, nitrides, and boron for which conventional melting techniques present a series of inconvenient.

The practice possibility for using solar furnaces in steel melting can also be studied. The performances of such a solar furnace must not be special because there is sufficient temperature of 2000–2500°C.

In the future studies, there may be a higher interest for melting some other metals more expensive than steel like titanium, zirconium, and molybdenum. In this case, it must be assured an inert protective atmosphere, and thereby the complications and expenses related to these must be taken into account.

Other applications of solar furnaces are impurities evaporation, zonal melting, fractionates crystallization, zirconium oxide extraction from zircon (zirconium silicate), and the materials studied under thermal shock conditions.
