Caracterização de cinzas de bagaço de cana como matéria prima para a produção de cerâmica


The aim of this paper is to analyze the sugar cane bagasse ash from three Sugar and Alcohol Plant of the State of São Paulo – Bazil. We intend to show the discrepancies between them, so that this raw material could be used with greater quality control in ceramic industries. The bagasse was analyzed by differential scanning calorimetry (DSC), thermogravimetry (TG) and scanning electron microscopy. The ashes were analyzed by X-ray diffraction, X-ray fluorescence, scanning electron microscopy, energy dispersive spectroscopy, and granulometric separation. The results indicated that the content of SiO ₂ ranging from 50-80% by weight depends on the granulometry of bagasse and the region where it was collected. The analysis of X-ray diffraction indicate SiO ₂, Fe ₂ O ₃, K ₂ SO ₄ and Mg ₂ P ₂ O ₇ as crystalline phases.
