Estudio y caracterización física de arenas ferrosas depositadas sobre sustrato vítreo con aplicaciones industriales

Abstract

In the present work of investigation were studied and characterized black sands of the beach El Suspiro located in Mompiche, with the purpose of applying them as covering on a glassy substratum. For this plan there were realized analyses of Diffraction of X-rays (DRX), RAMAN and microscopic with the intention of characterizing physics, chemistry and mineralogically a population of black sands. Once obtained the covering, one proceeded to realize mechanical tests of fragmentation and impact with ball under the standard EN 14179 for safety glasses. As for results one could determine that under the rate of temperature induced by the oven in the process of application of the covering the mechanical resistance to the impact diminished 30 %. Nevertheless there did not get lost the magnetic and thermal capacity of the black sands. Finally, there was obtained the composition of the minerals that constitute the black sands, being the principal ones the ilmenite and the lodestone with percentages of 45 % and 35 %, respectively, which justifies thanks to his high percentage of elements iron and titanium his employment in diverse applications to industrial level.
