Description

Solar energy is one of the most promising renewable energy options among those available for achieving a considerable amount of energy - saving and carbon emission reduction and for the replacing fossil fuels because can created electrical energy and heat without polluting the earth. For the first time in the 2015 year the optical properties of black zirconia are investigated for the solar applications [1]. Black zirconia ceramics have many problems, such as uneven color and poor phase stability. In this paper zirconia ceramics doped with the varied Fe2O3 contents were prepared by a high temperature solid state reaction process.
Obtained samples were characterized by investigations of analysis of X - ray diffraction (XRD), Fourier – Transform Infrared (FTIR), UltraViolet – Visible (UV-Vis), Photoluminescence (PL) and Electron Paramagnetic Resonance (EPR) spectra. Increment of Fe2O3 content has a substantial effect on the promoting of the thermal and solar to thermal efficiencies of the zirconia composites.
