Helium-3 (3He) is a noble gas that has critical applications in scientific research and promising application potential as clean fusion energy. It is thought that the lunar regolith contains large amounts of helium, but it is challenging to extract because most helium atoms are reserved in defects of crystals or as solid solutions. Here, we find la...

Photoanode is an essential part in dye sensitized solar cells (DSSC). Semiconductor materials, such as TiO2, ZnO, and SnO2, are commonly used as photoanode material. In this study, DSSC photoanode was fabricated using TiO2 obtained from Bangka ilmenite concentrate by caustic fusion method followed by water leaching, acid leaching, and sol-gel react...

New 18O/16O β-factors have been calibrated against temperature for titanite (considering the principal isomorphic substitutions Al + F ⇔ Ti + O, Ti + O ⇔ Al + OH, Ti + O ⇔ Fe3+ + OH) and ilmenite (accounting for Fe ⇔ Mg substitution) for the first time using the frozen-phonon approach of the density functional theory. The equilibrium oxygen isotope...
Ilmenit se v naravi pojavlja kot akcesorni mineral v mnogih kamninah. Ker je zelo obstojen, se v procesih preperevanja pod vplivom vode in vetra kopiči v obliki težkih peskov, ki predstavljajo najpomembnejšo ekonomsko surovino za pridobivanje titana. Namen magistrske naloge je bil pokazati, da lahko naravne ilmenitne težke peske, ki so ekološko spr...

The paper presents results of thermokinetic investigation of the hazard-type reaction of Norwegian and Australian ilmenite ores with sulfuric acid, modified by the addition of elemental sulfur, to increase the process safety in industrial conditions. In the reactions of both ilmenite ores the addition of sulfur caused a reduction of the thermal pow...

Abstract—A hypabyssal intrusive of fayalite plagiogranites of Mount Kastel intruded into the Yuzhnoberezhny uplift of the Gorno-Crimean tectonic Zone of the Crimean Cimmerids. Plagiogranites cross and contact metamorphosed intensivly dislocated flysch strata of the Taurian series T2 –J1, the bodies of island arc gabbroids of the Early Bajocian Perv...

Abstract—The experimental works of Russian and foreign researchers focused on the behavior of ore minerals, such as titanomagnetite and ilmenite in an oxidizing environment in different temperature ranges, have been analyzed. The optimum temperature conditions and time interval for oxidizing roasting of mineral aggregates have been substantiated. T...
Abstract The world is moving at a fast pace in the consumption of non-renewable natural resources, causing several ecological problems. The search for the cost reduction by implementing renewable energies implies in the optimization of the manufacturing processes parameters of consolidated technologies, such as solar thermal energy collectors. One ...

A new concept for producing highly pure Ti metal powder from ilmenite (FeTiO3) is proposed in this article. Titanium nitride (TiN) or titanium oxycarbonitride (TiOxCyNz) could be synthesized in the first step via the simultaneous carbothermal reduction and nitridation (CTRN) of FeTiO3 to remove oxygen roughly. To separate oxygen completely, high-qu...

We report the first occurrence of magmatic haggertyite (BaFe6Ti5MgO19) from the Miocene lamproites of the West Kimberley region of Western Australia. This contrasts with the metasomatic formation reported in an olivine lamproite host at the type locality, Prairie Creek, Arkansas. Haggertyite occurs in the groundmass of a diamondiferous olivine lamp...
