“…On the other hand, the use of highly reducing conditions for the synthesis of perovskite-like vanadates implies a large oxygen deficiency. In perovskitelike oxides, a transition to domainized brownmillerite-like structures is possible, as is well-known for strontium ferrite [32], although additions of V and Mo to strontium ferrite "smooth out" these transitions and reduce domain wall thickness [33][34][35]. The perovskitebrownmillerite transition may be preceded by the ordering of oxygen vacancies.…”

Perovskite–like vanadate–molybdates are interesting from the point of view of their metal–like conductivity, which combines the correlated and free electron nature. A series of CaV1–xMoxO3–δ solid solutions was considered near the Mo concentration x = 0.4, where a difficult–to–perceive structural transition was previously detected. High-resolution transmission electron microscopy revealed the phase separation of CaV0.6Mo0.4O3–δ into nanoscale regions with different ratios of V and Mo concentrations, despite X–ray diffraction analysis exhibiting a homogeneous perovskite structure. The rest of the compositions from the CaV1–xMoxO3–δ series do not show phase separation. The nonmonotonic behavior of the conductivity and linear expansion of CaV1–xMoxO3±δ was shown when the oxygen activity in the N2-H2-H2O gas mixture was varied, which is mainly determined by the partial decomposition of the perovskite phase. Against this background, the behavior of the electrical properties of the CaV1–xMoxO3±δ individual phase remains unclear.

“…The easiest way to get PBP is obtained from the CNPV curve. The value of PBP is determined by understanding the time when the CNPV/TIC value reaches zero for the first time [31]. b Gross Profit Margin (GPM) or gross profit is a type of profit that is calculated by subtracting income for one period from the cost of goods sold.…”

The purpose of this study was to examine two models of the economic feasibility of producing nanoparticle of dysprosium-doped cobalt ferrites by sol-gel auto-combustion method, from a laboratory scale to an industrial scale, including technical analysis and economic evaluation. Various economic evaluation parameters were analyzed to report the fabrication potential of dysprosium-doped cobalt ferrites nanoparticles in the case of the time required for a speculation to recover its total initial expenditure (PBP), the conditions of a generating project in the production function in years (CNPV), undertaking profits, etc. The results of the economic feasibility study on the production of dysprosium-doped cobalt ferrites nanoparticles showed that all parameter changes gave positive values, demonstrating that this project might have been practical to run commercially and on a large scale. Technical analysis to produce 26.4 tons of dysprosium-doped cobalt ferrites nanoparticles per year reveals that investment will be gainful then afterward more than three years. This project emulates PBP capital market guidelines due to the crisp return on investment. Estimates range from ideal to worst-case states in production to ensure project feasibility, including labor, sales, crude materials, utilities, external factors, and taxes.
