| Popis: | The present study evaluated the influence of two sugarcane bagasse ash (SCBA) beneficiation processes (sieving and high-energy milling) as an alternative to evaluate its absorption potential for application as a raw material for the production of solar absorber films. It was noticed that the absorption levels of all the samples were higher than 90% and that the SBCA has predominance of SiO2 corroborated by the mineralogical analysis. The thermal behavior of all the samples was similar among each other, presenting a total mass loss corresponding to 8.5%. As the ash is able to maintain a thermal stability in the temperature range of 100°C to 1000°C, and the chemical and mineralogical composition favors the absorption of solar energy, SCBA has proven to be favorable for application as raw material of selective solar surfaces. |
