The present work is a review of the substantial effort that has been made to measure and understand the effects of corrosion with respect to the properties, performance, and durability of various forms of silicon carbide and silicon nitride. The review encompasses corrosion in diverse environments, usually at temperatures of 1000 °C or higher. The environments include dry and moist oxygen, mixt...

The aim of this research work was the evaluation feasibility to utilize industrial by-products, such as electric arc furnace steel slags, for sustainable concrete production. paper evaluated environmental and mechanical properties slags concrete, respectively. Specifically, release contaminants from investigated by leaching test fresh hardened were a mixture designed with partial substitution (...

Samples of concrete contain various waste materials, such as iron particulates, steel balls of used ball bearings and slags from steel industry were assessed for their anti-radiation attenuation coefficient properties. The attenuation measurements were performed using gamma spectrometer of NaI (Tl) detector. The utilized radiation sources comprised 137Cs and ⁶⁰Co radioactive elements with photo...

The report aims at improving knowledge of the interaction between poplar and heavy metals and at parsing the poplar ability to remove or render harmless such inorganic elements contained in residual slags of leatherindustries. Scions of Populus x euramericana, clone I-214, were grown outdoors, in pots, in inert soil, pruned for a single shoot and subjected to three treatments: non-amended (C), ...

During carbon steel manufacture, slag residues are generated to remove material impurities from liquid metal and thus control the quality of carbon steel. As the utilization of secondary metallurgical slags is not as efficient as those of primary slags, a comprehensive characterization of steel ladle slag was performed. Pseudo-total concentrations of a wide range of elements were determined dur...

In this study, novel slags with a high basicity index were used to refine silicon melts carbon dioxide injection effectively remove Ti from metallurgical-grade silicon. Different compositions of the initial slag used, and samples obtained during refining. The results indicate that Ti-removal rate initially increased an increase in index, it decreased after exceeded 1.4. During refining, emulsif...

In this research, the influence of chemical composition of slags and the melting rate on the impurity of commercial grade iron in ESR processing has been investigated.The chemical composition and microstructure studies were evaluated, using spectrophotometer,OMand EDX analyses attached to SEM.The results show that ESR process has successfully reduced the amount and size of inclusions. In some c...

A high titania slag that is used as a feedstock for TiO2 manufacturing obtained by ilmenite smelting (FeO.TiO2). The composition of the dependent on mineral preparation, i.e., in our study. At laboratory scale, slags are mostly using raw material. An easy and simple way would be to prepare synthetic individual components heating them temperature furnace. has oxidizing nature requires an inert a...
