Caracterização do pó de basalto para uso como biomaterial

Abstract

In this study, the composition of the basaltic rocks found in the basaltic flow of Francisco Beltrão, in the southwest region of Paraná, was studied, in addition to their uses and feasibility of application in the production of biomaterials, as an alternative to their disposal, which is commonly their destination. Final. For this to occur safely, it was necessary to carry out a chemical and structural analysis of the rock, through chemical characterization tests. Initially, the basalt was harvested in natura and subjected to a grinding process to obtain the rock powder. Then, chemical characterization tests were carried out: X-ray diffraction (XRD), X-ray fluorescence (FRX), Fourier transform infrared spectroscopy (FTIR) and DSC-TGA thermal analysis. In the DRX and FTIR analysis, the presence of the anorthite and albite phase, belonging to the group of plagioclase feldspars, was observed. The FRX test provided the chemical composition of the material, which is mainly composed of oxides, namely silicon dioxide (SiO2), iron III oxide (Fe2O3) and alumina (Al2O3). Thermal analysis provided the mass loss content of the sample, as well as its melting temperature. It was also possible to observe the absence of chemical reactions or melting at room temperature, proving the stability of basalt. In general, the use of basalt in the manufacture of biomaterials is feasible, since it does not contain compounds harmful to human health and is stable and may be an alternative to the final destination of this rock dust.
