Tratamento químico da poeira de aciaria elétrica e utilização na síntese de Fer...
Lima, Edilan SilvaThis work presents a study on the use of solid inorganic residue from steel industry , electric arc furnace dust (EAFD), using as a basic compound for the production of advanced ceramics, zinc ferrite ( ZnFe2O4 ) through a chemical treatment. The EAFD is a waste by product of steelmaking generated in steel mills that operate electric arc furnaces (EAF) , which is classified as a solid hazardous waste Class I ( ...
Zinc ferrite nanoparticles via coprecipitation modified method: glycerol as str...
Lima, Edilan Silva; Costa, Luelc Souza da; Sampaio, Gabrielle R. L. M.; Oliveira, Edipo S.; Silva, Erandir B.; Nascimento, Hélio O.Coprecipitation is one of the most practical methods used to synthesize ferrite nanoparticles. Fine characteristics of these materials can be improved by means of a series of modifications in the synthesis method. In this paper we present a study of influence of glycerol as structure directing and stabilizing agent in the synthesis of zinc ferrite nanoparticle, exploring its chelating capacity and oxidation. Th...
Nanopartículas de ferrita de zinco via modificação do método de coprecipitação:...
Lima, Edilan SilvaIn the present thesis, the relevance of glycerol is investigated as a driving agent in an the synthesis of zinc ferrite nanoparticles with particular physical properties, by means of a modified coprecipitation method. The studied materials include two series of zinc ferrite samples and its precursors obtained with or without glycerol throughout different stages during the synthesis process. The structural and m...
