Preparation and characterization of SrBi2Nb2O9 thin films made by polymeric precursors
(1998-10-01)
A polymeric precursor solution was employed in preparing SrBi2Nb2O9 (SBN) powder and thin films dip coated onto Si(100) substrate. XRD results show that the SBN perovskite phase forms at temperatures as low as 600°C through ...
Analysis of pig iron desulfurization with mixtures from the CaO-Fluorspar and CaO-Sodalite system with the use of computational thermodynamics.
(Ouro Preto, 2013)
This work aims at the use of computational thermodynamics in the study of desulfurization of pig iron through CaO-Fluorspar and CaO-Sodalite mixtures. Experiments were performed with the addition of different mixtures from ...
Hot metal desulfurization by marble waste and fluorsparDessulfuração de ferro gusa utilizando resíduo de mármore e fluorita
(Escola de Minas, 2012)
The objective of this paper is to present an analysis of the use of residual marble mixtures in the pig iron desulfurization process. The study involved the use of: marble waste, fluorspar, lime, and hot metal. Four mixtures ...
