1. Comparative study of porosity and pores morphology of unalloyed iron sintered in furnace and plasma reactor
Samples of unalloyed iron were sintered in the presence of an abnormal glow discharge using a confined anode-cathode configuration. The samples were placed on a holder acting as the discharge anode inside an AISI 1020 steel hollow cathode. Heating of the outer cathode was obtained by the bombardment of ions and energetic neutral particles. As a consequence o

2. ELECTRICAL RESISTIVITY IN CONCRETE WITH DIFFERENT CONCENTRATIONS OF BLAST FURNACE SLAG AND A CHEMICAL ACTIVATOR / RESISTIVIDADE ELÉTRICA DE CONCRETOS COM DIFERENTES TEORES DE ESCÓRIA DE ALTO FORNO E ATIVADOR QUIMICO
The integrity of the rebars in reinforced concrete structures is related to the chemical and physical protection provided by the concrete layer that covers the steel. The destruction of the passivation layer precedes the onset of corrosion. Once the corrosion process starts, its rate of propagation will depend on the electrical resistivity between cathode an

3. CINÉTICA DO ELETRODO DE FES2 / FE EM SAIS FUNDIDOS / FES2 / FE ELECTRODE KINETICS IN MOLTEN SALTS
In this work the measurement of the critical kinetics parameters of iron disulphide electrochemical reduction in molten chloride halides mixture was made. This cathode is applied as alternative material in high technology systems, such as, solar energy collector`s components, anode depolariser for hydrogen production and cathodic materials for high energy de

4. Experimental and computational termoelástica analysis for finite elements of the external wall in armed concrete of an anode baking oven / Análise termoelástica experimental e computacional por elementos finitos da parede externa em concreto armado de um forno de cozimento de anodo
This thesis presents a study about the behavior of a reinforced concrete structure subjected to high thermal variations. The structure under investigation is the external wall of an anode furnace used in Aluminum production, and is subjected to thermal variations in the range of 125C (2282 F) due to the furnace operation. The main motivations for the study w

5. Caracterização de escorias e recuperação do silicio / Characterization of slag and recovery of the silicon
Metallurgieal Grade Silicon (MGSi) is produced by a well-established industrial process that consists of the carbo-reduction of quartz in a submerged are fumace under high temperature. The process is an intensive energy consumption method (13 - 15 kWh to each kilogram of produced MGSi). After tapered, the MGSi is submitted to some purification stages in orde
