Development of Sustainable MgO–C Refractories Using MgO–C Recyclates and a Novel Eco‐Friendly Fructose–Tannin Binder Crosslinked With Citric Acid

open access: yesAdvanced Engineering Materials, EarlyView.
This study develops sustainable MgO–C refractories using recycled materials and eco‐friendly fructose–tannin binders. The enhanced performance of citric acid as a cross‐linker and functional additives on mechanical and thermomechanical properties was examined. Characterization included strength tests, immersion trials, and microstructural and inclusion

OIL- AND GAS-BEARING POTENTIAL SEA AREAS OF THE EAST EUROPEAN PLATFORM

open access: yesГеологія і корисні копалини Світового океану, 2019
The history of geological exploration and search of oil and gas in the sea areas of the Eastern European platform — the Sea of Azov-the Black Sea and Barents Sea is illustrated. The structure of hydrocarbon deposits is described.

Some mineralogical data on genesis of magmas of the Carpathian region

open access: yesГеофизический журнал, 2010
A brief characteristics of minerals of magmatic rocks is given: pyroxenes, olivine, spinel, garnet, tridymite. Composition of clinopyroxenes indicates two geodynamic regimes in Mesozoic: intraplate (continental crust destruction) and spreading one ...

Numerical Modeling of Tank Cars Carrying Hazardous Materials With and Without Composite Metal Foam

open access: yesAdvanced Engineering Materials, EarlyView.
Large‐scale puncture models consisting of hazardous materials (HAZMATs) tank car with protective steel–steel composite metal foam (S–S CMF) are solved numerically. Tank car plate with added 10.91–13.33 mm thick S–S CMF layer does not puncture. Protective S–S CMF absorbs impact energy, reduces plate deformation, and prevents shear bands formation ...

Impact of Pre‐Oxidation Treatments on a Recycled MgO/Steel‐Composite as Carbon Free Anode in Aluminum‐Electrolysis Environments

open access: yesAdvanced Engineering Materials, EarlyView.
Cermets (60 vol.% AISI 316L stainless steel, 40 vol.% recycled MgO), intended for use in aluminum electrolysis, were pre‐oxidized in three furnaces with different heating technologies and subjected to a cryolite corrosion test. The different atmospheres influenced the formation of oxide layers, which in turn affected corrosion resistance and ...
