Problem
Combining multiple iron, titanium, cobalt, and carbon phases with controlled particle size and homogeneity is difficult using conventional high-temperature material processing.
Why it matters
A reproducible multiphase magnetic or semiconducting powder could support catalysis, environmental, and energy-material research if application-specific properties are demonstrated.
Approach
A solution process combines titanium butoxide with cobalt and iron nitrates, adds dextrose monohydrate, dries the mixture at 150 °C, and calcines the solid. The product integrates Fe2TiO5, Fe1.766O3, TiO2, CoFe2O4, and carbon in granular spherical particles.
Who may benefit
Potential beneficiaries include mixed-oxide producers, catalyst and magnetic-material researchers, environmental-material laboratories, energy-storage groups, and specialty ceramic developers.
Potential value
The route integrates four crystalline oxide phases plus carbon in one powder with specified elemental composition, crystallite size, and particle morphology.
Background
Background
Multiphase oxides can combine magnetic, catalytic, semiconducting, or electrochemical behavior, but uncontrolled grain growth and phase separation can reduce reproducibility. Conventional processes may also require long treatments or complex steps. The publication introduces an iron-titanium-oxide, iron-oxide, titanium-dioxide, cobalt-ferrite, and carbon composite prepared through solution mixing and calcination. The supplied record supports composition and structural characterization only; it does not provide catalytic, magnetic, electrical, electrochemical, remediation, durability, or application-specific device-performance measurements.
Technology overview
Technology overview
A titanium-butoxide, ethanol, and acetic-acid solution is added to cobalt-nitrate and iron-nitrate solution. Dextrose monohydrate is then introduced while stirring at 150 °C until a solid forms. Calcination at 600–800 °C for 1–5 hours yields the five-component powder. The patent specifies elemental-content ranges, 40–80 nm crystallites, and spherical particles with a 40–80 nm average diameter. XRD, EDX, SEM, and HRTEM characterize the laboratory product.
Potential applications
Potential applications
- Multiphase oxide powders for catalyst screening.

- XRD, EDX, SEM, and HRTEM characterization are described.
Development stage
Development stage
Laboratory synthesis and XRD, EDX, SEM, and HRTEM characterization are described; scale-up and any functional application performance are not established.
Commercial opportunity
Commercial opportunity
The powder may interest specialty oxide, catalyst, magnetic-material, or electrode developers. Commercial assessment requires repeatable phase purity and yield, scale-up and furnace economics, powder safety, and independent application-specific magnetic, catalytic, electrical, electrochemical, remediation, aging, and comparative performance data. No functional performance is established in the supplied evidence.
