Six-Phase Nanocomposite Material Production

Official patent title

Nanocomposite material fabrication

Arabic title: تصنيع مادة مركبة نانوية

Invention

Problem

Multiphase nanocomposites can suffer from phase incompatibility, inconsistent morphology, and poorly controlled crystallite size. Fabrication must reproducibly generate the intended phases before application performance can be optimized.

Why it matters

Controlled titanium- and magnesium-oxide composites may provide useful interfaces for future catalytic, dielectric, electrochemical, or sensing studies, subject to cadmium-safety management.

Approach

The disclosed material integrates Mg0.6Ti2.4O5, MgTiO3, tetragonal and orthorhombic TiO2, CdO, and carbon in spherical nanoscale particles prepared from solution precursors followed by high-temperature calcination.

Who may benefit

Potential beneficiaries include advanced-ceramics researchers, catalyst and sensor developers, electrochemical-material laboratories, university materials centers, and specialty-powder manufacturers.

Potential value

The patent defines six material components, elemental ranges, 50–130 nm spherical particles, 40–80 nm crystallites, and a stepwise precursor-to-calcination fabrication route.

Background

Titanium oxides and magnesium titanates are studied for optical, dielectric, catalytic, and electrochemical behavior. Combining multiple phases can create useful interfaces, but uncontrolled synthesis may yield heterogeneous products and inconsistent properties. Cadmium oxide adds another electronic or catalytic component while also introducing significant toxicity and disposal considerations. The disclosure focuses on defining phase composition, elemental content, morphology, and a solution-based preparation route. It does not tie the material to one validated end-use performance test in the supplied evidence.

Technology overview

The composite contains orthorhombic Mg0.6Ti2.4O5, hexagonal MgTiO3, tetragonal and orthorhombic TiO2, cubic CdO, and carbon. Spherical particles are claimed at 50–130 nm and crystallites at 40–80 nm, with specified O, Ti, Mg, Cd, and C atomic ranges. Titanium butoxide, ethanol, and acetic acid are added to magnesium- and cadmium-nitrate solution; L-sorbose is introduced at 200 °C, the mixture is dried to a solid, and it is calcined at 600–800 °C for 1–5 hours.

Potential applications

Multiphase oxide-material research.
Catalyst and photocatalyst screening.
Dielectric and electronic material studies.
Electrochemical electrode-material evaluation.

Evidence-supported advantages

Combines several titanium- and magnesium-containing phases.
Defines particle and crystallite-size ranges.
Provides elemental-composition windows.
Uses a stepwise solution preparation route.
Offers tunable calcination conditions.

Development stage

Laboratory synthesis and phase, elemental, particle, and crystallite characterization are described; reproducibility across batches, cadmium leaching, and application-specific catalytic, electrical, mechanical, or electrochemical performance were not established. The development stage was not independently verified.

Commercial opportunity

The material is a platform powder rather than a validated product. Licensing or collaboration should begin with an application-specific screen, property benchmarks, batch reproducibility, phase stability, cadmium leaching and worker exposure, safe waste handling, precursor and energy cost, scale-up of mixing and calcination, and compliance with restricted-substance and environmental regulations.
